Why there is more than price to choosing a web hosting company

by: Chris Hudson
29 June, 2009

Choosing a hosting company for your website should be an informed decision, because once taken your choice will affect how your website is seen (or even if it can be seen) by the rest of the world. It can also influence whether your website is picked up by search engines, how it ranks in their SERPs (Search Engine Results Pages), which obviously directly alters the amount of traffic to your site. It may even result in your site being blacklisted by search engines if you end up hosting your site in a “bad neighbourhood”!

Yet, despite all these ramifications, the choice of host is often made by the simple expedient of choosing a “free” host or a “one cent” host, or because someone knocks £5 off the price for the first 3 months.

Is your business worth so little to you that you begrudge paying the price of a pizza to give it the advantages of a secure, fast and search engine-friendly home?

Beware of hosts bearing big numbers!

People are often blinded by by mind-numbingly huge numbers thrown at them, particularly by the very large hosting companies. Favourites are bandwidth and hard disk space - the truth is less than 1% of their customers will get close to using either the quoted bandwidth figures or the hard disk space. So effectively these hosts are able sell that same unused space and bandwidth again and again, cramming more free accounts on the same server. Distracted by this sleight of hand, customers will often forget to check out even more important factors of their new hosting account.

In fact, the key criteria to a fast host are the type of CPU in the server, the CPU speed, the amount of RAM available to your website as well as the overall number of active websites being operated from the server.

On a shared web host account - the commonest kind, these details are often lacking or vague on the sign up pages. The hosting company will hope you’re mesmerised by the promise of 15 Terabytes (15,000Gb) of bandwidth, etc. That is because the free host may not want to reveal how old, slow or overcrowded is the server being employed on your behalf. Particularly with free hosts, the more websites a hosting company can put on a single server the lower the cost for them but the smaller your share of the crucial server resources, like CPU time and memory, your website will receive and the slower your website will appear to be to its visitors.

Server uptime and when is a guarantee not a guarantee?

To ensure the availability of your site you should ask your free host, what is the guaranteed uptime (website availability) in the Service Level Agreement? There is a SLA right? Are its provisions guaranteed? We mean a money-back guarantee, of course. Oh, wait a minute - you’re not paying them anything so there is no “money-back” guarantee. In fact, without a financial penalty of any kind there is no “guarantee” at all - after all they can promise you the moon but it’s worthless - just words. Not the sort of guarantee you’d want to base your business website on right?

Moreover, is there 24/7 tech support? If not, are their working hours compatible with the timezone in which you live? In you live in London do you want to depend on Texas time! What happens if your business website suddenly becomes “unavailable” while their tech support is offline twelve hours a day?

Also is the server itself housed in a data centre with redundant connections to the internet, so as to avoid down time; has the data centre got backup power supplies? How about proper fire and intruder prevention systems? There are different types of data centre, they are not all as resilient as you may expect. Here in the UK they are officially categorised from Tier One (Basic) to Tier Four (Super Duper - used by Global companies).

Leaving aside the free or one cent hosts for a second, another common mistake that business users make is to let their web designer host their newly-created website. This is an understandable decision on the part of the client. He’s probably never setup a hosting account or FTP’d html files to a remote server and here is a designer saying I’ll do it all for £50 a year, it’ll be up and running today and you don’t have to mess around technically with anything. Yet it can be terrible decision. You need to ask the sort of questions you want answering by any hosting company. Is designer’s server in a data centre or is the server hosted on an spare computer in your web designer’s office at the end of a domestic broadband connection? Don’t laugh, one UK company discovered several hundred websites being hosted on a teenager’s home computer! Don’t panic if you are hosted by your designer, most adopt a professional attitude to hosting clients’ websites but do make sure he is hosting your site in a data centre, and he has technical cover for your website if and when he goes on holiday.

As you can see, web hosting companies are simply NOT the same the world over or even in the same country.

More pitfalls of free hosting

If you are going to choose a host on price then you will miss out on the best hosts. Even simple logic must tell you that! Many cheap or free hosts work on a principle of “never mind the quality, feel the width”.

They make up for their lack of reliability through utilising cheap or outdated servers and switches or failing to provide offsite backups or redundancy but blinding you with low prices or even free hosting in return for letting them show their adverts to your visitors!

They will make unsubstantiated claims of 99% uptime. Take a look at twitter some time and see the parade of people tweeting about their website/server going down. Even if they could make a 99% uptime figure, that still means your website will be down for nearly three and a half days a year and downtime will effect your search engine rankings if their spiderbot comes along and it cannot find your site. Here in the UK at Intrahost we have a written service level agreement that guarantees our customers an uptime of 99.99%. Over the last two years our performance has exceeded even that guarantee.

Perhaps one of the biggest dangers of a free host is the worry that you have no idea about the nature of the other sites being hosted on your overworked server. If any other domain on your crowded free server is a spammer, a phishing site, a porn site affiliate or a warez source you can be sure that search engines will log the IP address of that server and will probably blacklist its IP number.

Your site will have the same blacklisted IP number as the dodgy sites and you could find you’re delisted by all the major search engines. It’s what’s known as being hosted in a “bad neighbourhood”. No SE listing = no traffic, so just how much of a bargain is that free hosting now?

In which country should I be hosted?

You will also need to look at the country in which your server is located. It can have a huge influence on your Google ranking and indeed it can alter the rights you have in relation to your deal with your web hosting company.

In the EC strong protections exist against unfair business practices, and here in the UK, government agencies ensure that advertising is decent, honest, legal and truthful and trading standards departments monitor how UK enterprises carry out their day-to-day business. That sort of government oversight is simply not available in most countries offering cheap deals.

Is your website worth more than a round of drinks or a pizza?

The cost of being hosted by a reliable company is comparatively little especially for even a small business. Despite this the mere existence of free hosts seem to make many people resentful and unwilling to pay even a modest price.

A year’s web hosting with Intrahost starts at less than £60, I paid more than that just to see one English Premier League match last season - ninety minutes of over-hyped football against 8760 hours of reliable web hosting with 24/7 technical cover!

With that, I’m off to the pub with a friend for a pint. A round of drinks, two beers, will cost me more than one month’s hosting in the UK with Intrahost - £4.95. Puts it all into perspective doesn’t it?

WordPress 2.8.1 beta upgrade is available

by: Chris Hudson
23 June, 2009

Many Intrahost clients use their web hosting account to run a blog - usually based on WordPress and last week saw the release of a major update, version 2.8.

Now, if you updated last week to the latest version of Wordpress you may be aware of a few bugs kicking around; problems with themes, the dashboard, incomplete page loads and the automatic upgrade!

You’ll be pleased to now that the WordpPress developers have taken their first steps towards fixing these bugs with the release of WordPress 2.8.1 beta.

Download WordPress 2.8.1 beta

Here are a few of the bugs fixed so far

  • Many themes were calling get_categories() in such a way that the command failed under 2.8.  Now 2.8.1 works around this no changes are necessary to these themes
  • Users were running out of memory when loading the dashboard, resulting in an incomplete page. So Dashboard memory usage has been reduced.
  • Thankfully the automatic upgrade no longer accidentally deletes files when cleaning up from a failed upgrade!
  • The rich text editor will now load, avoiding compression issues.

To automatically upgrade from 2.8 to 2.8.1 Beta 1, follow these instructions.

WordPress can be automatically installed by Intrahost clients who are using the Fantastico add-on that comes as part of the cPanel control panel on their Linux based web hosting account.

PC Pro reviews HP ProLiant DL360 G6 server - our virtual dedicated server!

by: Chris Hudson
17 June, 2009

Just as we announce the availability, from July, of our new virtual dedicated servers based on the HP ProLiant DL360 G6 we see that the renowned PC Pro magazine has just released an online review of the 1U web server.

The sixth-generation rack server scored an impressive 5 out of 6 stars. PC Pro praised the server as having “an excellent range of features with plenty of storage and expansion potential, plus a keen eye on value and power management “.

When you see the three thousand pound price tag you’ll realise why a virtual dedicated server makes so much more financial sense for all but the largest businesses.

Read the PC Pro review of the server we are using for our virtual dedicated server hosting package here at Intrahost in the UK.

Here’s our own take on the web server we have purchased for use in our UK data centres.

Meet Intrahost’s new HP virtual dedicated servers

by: Chris Hudson
16 June, 2009

Customers can now opt for UK-based, virtual dedicated servers using the very latest HP ProLiant servers aimed at SME and users alike. Here’s a short video so you can see the ProLiant DL360 G6 server you will be using and hear about some of its key benefits:

Video about the HP ProLiant DL360 G6

As a virtual server user your main concern will be: will my web server be fast and value-for-money?

Here the Intrahost ProLiant DL360 wins hands down on both counts.

The web servers are are powered by very fast Dual Quad Core Intel 5500 processors, and Intrahost have fitted each ProLiant DL360 with a massive 72GB memory to assist the processing speed. All Intrahost servers will be connected to our high-end HP fibre SANs through HP Procurve multi-gigabit fibre, fabric switches - so there’ll be no connectivity bottlenecks or reliability problems to slow down the server.

Intrahost always aim to bring-value-for-money to our hosting solutions and the ProLiant DL360 assists in both its physical size and components. Two of the main factors in hosting costs are the rackspace and the power used by a server.

The ProLiant DL360 G6 is built as a slim 1U server (but still manages to find room for up to eight hard drives) and so rackspace costs are at the minimum.

Intrahost’s ProLiant servers also win out on keeping down power costs too, each DL360 G6 server uses 40% less power than the previous G5 model and is up to 100% more energy-efficient in performing its tasks. The DL360 G6 uses flexible SmartArray technology to increase performance while, at the same time, saving energy. It uses sensors for power and cooling that enable it to save power by slowing cooling fans when not needed and turning off power to unused sections of the server.

Keeping size and power usage to a minimum means that the HP Proliant DL360 G6 servers will help Intrahost provide you with a fast, green, cost-effective solution to you virtual dedicated server needs.

Intrahost’s virtual dedicated servers start from just £34.95 per month. All have unmetered bandwidth and you have a choice of OS: Windows or Linux and you may have the Plesk server control panel installed on your VDS if you wish.

Guide to UK colocation

by: Chris Hudson

Overview

Colocation is a service where you place your own web server and network equipment in an Internet data centre, or colocation facility. But there are far more criteria to consider with this option than simply the cost of buying the server and the monthly fee charged by the hosting company.

Usually, the server owner will deal with the data centre through a hosting company such as Intrahost. Hosting companies situate their own servers and colocated servers in the same racks in the data centres.

Your hosting company, like Intrahost, will deal with the data centre on your behalf. The data centre will be responsible for providing your server with a reliable high speed connection to the Internet, uninterruptible power supply, air conditioning and physical security from fire and theft.  There are different standards of data centre in the UK, referred to as “Tiers”. Only Tier 2 data centres and above have redundancy for power, telecoms and air conditioning which gives them a greater capacity to continue working in the aftermath of a major event e.g. major electrical blackout in the vicinity of the data centre. The data centre you end up in will usually be directly related to your choice of web hosting company. Although a few hosts, like Intrahost, do offer you a choice of data centre, so that you may pick one close to you geographically that will make visiting your server easier. Physical access to your server is usually 24 hours a day.

Choosing colocation enables you to choose your own brand and specification of web server rather than one offered by your choice of hosting company. Dell rather than HP? It’s your call.

You will have to have staff capable of running the server, installing software, security updates, physically replacing malfunctioning parts eg disk drive, or adding more RAM. You will have to have someone on call 24/7. It is possible to outsource this function but it is a cost to be borne in mind when calculating the cost of your colocated server.

Cost of colocation

One of the drawbacks of colocation is the cost, much of it upfront before you are even online. A new web server can cost over a thousand pounds, and if you choose a second-hand server they will not be as fast as the latest dedicated servers offered by your hosting company, they will use more power (see below), they can be physically larger (see below) and you may still have to pay for updated software.

Additionally, you will have to pay the hosting company a monthly fee for rackspace in the data centre and for the bandwidth used by your server which is sometimes also referred to as “traffic”.

Anyone used to hosting a domain on a shared web server (as millions do), or even running a virtual dedicated server can be thrown when trying to work out the monthly cost of colocating a web server.

With shared web hosting monthly costs largely depends on size of disk space offered and total bandwidth available to be used by the user’s traffic over the month. e.g 250GB HDD plus 2000GB bandwidth. With virtual or dedicated servers the configuration of the server (CPU, RAM etc) usually factors into the price along with disk space and monthly traffic as before.

However, with colocation the configuration of the server is irrelevant as you are providing it and that includes the disk space. Traffic or bandwidth is relevant to cost but calculated in a different way.

With colocation it is rackspace used (or power used whichever is greater) plus bandwidth that determines your ongoing monthly costs.

However, with colocation bandwidth can have two meanings depending on which host you use. The one used by your colocation host can mean a huge difference in the price you pay per month and on your ability to budget for your web hosting costs.

There are two methods of measuring and charging for colocation bandwidth.

Firstly, capped bandwidth (or unmetered transfer), which is the method chosen by Intrahost. With this method the total amount of traffic or bandwidth used in a month is irrelevant. This is because you pay a fixed amount each month for a fixed amount of bandwidth that is available to your server per second e.g. 1 Mbps. This means that your server can handle up to 1 Mb of data each and every second. That figure is capped at whatever you have chosen and cannot be increased to cope with a sudden surge in demand. However, your server’s logs will indicate to you if demand is such that you need to increase your capped bandwidth to, say, 2Mbps.

Secondly, we have the real data transfer method; this involves paying for the total amount of traffic used by your server each month. While that might sound fair you have no idea how popular your server is going to be in the future, what if a domain is mentioned on TV or a video becomes a YouTube hit and thousands of downloads occur; you may find yourself hit with a huge monthly bill and so it is impossible to budget properly using this method. On the positive side this sort of burstable bandwidth does allow your server to cope with a sudden, unexpectedly high demand that may be caused by the appearance of an advert, news story or the release of a product without the server appearing to the end-user to be slowing down.

So, clearly bandwidth usage is going to be a major factor in your monthly cost but there are two other elements to consider.

Firstly, the amount of rackspace required by your server, because a data centre only has a finite amount of space in which to house web servers. A data centre provides metal racks with bays in which to house your servers. A rack can hold up to 42U of servers. The U is a unit of measurement. The vertical space used by a server is measured in Rack Units or U-Space; each U equals 4.45cm or 1.75″. When you look at buying your web server be sure to check this - it will normally be expressed as a 1U, 2U, 3U or 4U server. The bigger the U number the more your monthly cost will be as your server will be taking up more rackspace.

The other finite resource per rack is the power supply and, therefore, the more power-hungry your server is the more it’s going to cost you. This is one reason why more modern servers are better value in the long run as they are more efficient. For example, Intrahost’s new HP ProLiant G360 G6 servers use 40% less power and are 100% more energy efficient than just the previous generation of G5 ProLiants -  a point worth remembering if you are being offered a “bargain” deal on a three year-old server. Power usage is measured in amps.

Choosing your colocation

When you decide to colocate your web server with Intrahost you have to decide:

  • in which data centre do you want it physically locating? Manchester, Barnsley, Leeds, Hull or Sheffield
  • what is the U size of your server and its amp usage? Charges are based on whichever is the greater.
  • what is the dedicated bandwidth you want? 1Mbps or up to 5Mbps (if you’re not sure you can look at the price and pick the one within your budget)
  • installation type: you have a choice of either accompanied installation, this is where you would meet our engineers at the datacentre who would assist you with getting your equipment in, but the configuring of the equipment would be down to you,or  configuring the equipment first, then having it shipped to us for our engineers to install at the data centre; this is usually the quickest and cheapest option.

Apple Snow Leopard hits UK in September

by: Chris Hudson
9 June, 2009

Apple’s Snow Leopard will give Microsoft a chill with Apple claiming that it is faster than their Windows 7 OS which won’t launch until a month later.

Anyone purchasing a new Mac between June 8 and December 26, 2009 will be able to get Snow Leopard for a miminal upgrade price of around a tenner, with a bundle discount for those wanting to buy iLife 09 or iWork 09 at the same time.

The reason for the dramatically low price is that Apple is promoting Snow Leopard as an “upgrade” for existing 10.5 Leopard users, but it is technologically much more.

Apple’s approach is probably explained by the fact that Snow Leopard doesn’t contain a consumer headline-grabbing new feature such as Time Machine, Boot Camp, or even Quick Look.

Instead, most of the exciting developments of Snow Leopard are stuck “under the hood”, hidden away from the admiring glances of Mac fans, like the rewriting of nearly all system applications in 64-bit code and by enabling the Mac to address massive amounts of memory. Snow Leopard makes the Mac OS X faster, more secure and future-proof.

mac-osx-snowleopard

Practically, this 64-bit development means that Finder, Safari, Mail, iCal and iChat are now 64-bit native, (actually all system apps except DVD Player, Front Row, Grapher, iTunes and X11 have been rewritten in 64-bit), boosting performance and enabling them to use all the memory available in your Mac. All aspects of using your Mac will feel faster and more responsive. It also means that Snow Leopard can support up to 16 terabytes of RAM, approximately 500 times more than current Macs can address. Although Macs already benefit from having very little malware in their world, Snow Leopard means even greater security because 64-bit applications can use more advanced security techniques to defeat malware and hackers.

Grand Central Dispatch is a new technology to help make your Mac faster by making all of Mac OS X “multicore aware” and optimising its ability to allocate tasks across multiple cores and processors. This means efficient handling of tasks out of sight but with visible performance gains all over your Mac.

Snow Leopard’s OpenCL technology means that programs will be able to use the vast power locked up in your graphics processor for other general computing tasks or applications, unrelated to graphics! Consequently your Mac will gain an extra processor capable of trillions of calculations per second – now you’ll be able to justify paying the extra for that top of the range GPU your new Mac (that also just happens to be great for playing games).

Snow Leopard brings with it QuickTime X which includes a brand new player application with support for a much wider range of codec’s (needed to play different types of media file) and it fully utilises the media technologies at the heart of Mac OS X, Core Audio, Core Video and Core Animation, to produce greater efficiency and higher quality playback. QuickTime X also uses Mac OS X technologies such as Cocoa, Grand Central Dispatch and 64-bit computing.

QuickTime X supports HTTP live streaming, the same network technology that powers the web. Therefore, QuickTime X streams audio and video using any web server instead of a special streaming server and it works reliably with common firewall and wireless router settings.

Apple says, “HTTP live streaming is designed for mobility and can dynamically adjust movie playback quality to match the available speed of wired or wireless networks, perfect whether the video is watched on a computer or on a mobile device like iPhone or iPod touch”.

The final significant feature is Snow Leopard’s built-in support for Microsoft Exchange Server 2007 - just add your email address and password and the rest happens automatically! What does this mean to the Mac user who doesn’t see the benefit? You’ll be able to use Mac apps like Address Book, iCal, Spotlight, Quick Look and Mail instead of Outlook in Windows to access email, calendar invites and Global Address Lists and the other joys of working for Windows-centric employers.

So, although less flashy than some of its recent predecessors most of Snow Leopard’s benefits will be dramatically evident to end-users as soon as they begin to use their Mac – this is one very fast cat that will easily give Windows 7 a run for its money.
