10 tips on choosing a web host

by: Chris Hudson
16 October, 2009

When you begin to look for a host for your website or dedicated server you are immediately assailed by numbers; hard drive space, CPU speed, amount of dedicated RAM, bandwidth and more. Hosting companies today try to sell you hosting on the back of the technical specification.

It’s easy to believe that a good understanding of maths is all you’d need to pick the best web server hosting company. However, to make a good choice you need to resist the urge to leap for the best spec offered at the lowest price.

In fact, the numbers are just a minor part of the equation that you have to solve to find a good website or server host. The human element of the hosting company and the written agreement between yourself and the web hosting company are equally as important.

Here’s what to consider when choosing a web host:

  • Service levels - What you get for your money is largely determined by your host’s Service Level Agreement. Make sure you read it BEFORE things go wrong, so you know what will happen to correct a problem and what rights you have.
    Beware, I’ve seen a number of UK companies offering shared web hosting WITHOUT an SLA - you should avoid such offerings entirely. It’s like buying a car without a guarantee that it’ll even start up!

  • Tech support - You need to find out if support is 24/7, provided by phone and/or email. Is the telephone support number a premium rate line? Are the support staff trained engineers or is it outsourced to an Indian call centre? Here at Intrahost our lines are manned 24/7 by qualified engineers - in fact, they also provide the telephone IT support for some of the UK’s biggest companies.
  • Contract length - Beware of web hosting companies that tie you into long-term contracts for simple hosting like shared web hosting or VPS. Where’s their incentive to provide you with good service if you cannot terminate the agreement easily. Intrahost’s agreements below dedicated server level are from month-to-month so you are not tied into a long-term deal.
  • Scalability - This is tied to the flexibility of your agreement with your web hosting company. If you need to change your hosting requirements how easy is it to do so? Is there a financial penalty for doing so?
  • Nature of your hosting company - Is your hosting company a real host with their own servers in a dedicated data centre or are they merely a one-man band, reselling space on someone else’s servers that could be located anywhere in the world?  Are you comfortable with your info being stored on a web server in say, Russia?
    Do they have the expertise to solve a problem or are they relying on a supplier’s engineers? What happens if the one-man band suffers illness? Will he be there at 3am or during public holidays?
    Perhaps worst of all, what if the host company goes under? Will your data remain accessible in that event? What happens if the server is repossessed by a leasing company or the data centre shuts off connectivity or power?
  • Location - often overlooked, but you are far better off having a hosting company in the same country as your own location. If you are in the UK you have a raft of consumer legislation and local government departments dedicated to ensuring you get a fair deal for your money. All of which is lost if you go outside the UK. Even if you choose to host in advanced countries like the USA do you really want to try and resolve a legal difficulty from three thousands miles away in another time zone?
    Another reason for choosing a local host is that search engines like Google are becoming far more localised in creating their SERPs, and the physical location of your web server can play a major part in the decision by the search engine of when to display your results.
  • Data centre qualities: The web host’s servers must be housed in data centres rather than, for example, their own offices. The UK data centres are graded and you are looking for Tier 2 or greater. The grading represents qualities like:
    • Resilience - In order to guarantee 100% network uptime the centre needs at least two connections to the internet
    • Security - Has the data centre taken fire and intruder security measures?
    • Power - has it alternative power supplies? Usually UPS and diesel generators.
  • Performance monitoring - you should try to obtain performance data on your proposed web host - this is often displayed on their website
  • Testimonials - these are used by many sites; don’t be afraid to look up the people providing testimonials and ask them to confirm they still feel the same way about the host. Look up their website and gauge for yourself the end user experience of a website served by your proposed hosting company. I’ve lost count how many times I’ve looked up testimonials and received a 404 error page!
  • Guarantee - the SLA should offer a money-back, uptime guarantee - if there is no money-back then it’s NOT a GUARANTEE is it? Intrahost’s SLA contains its 99.99% server uptime guarantee.

Hosting Service Level Agreements and worthless guarantees

by: Chris Hudson

You do have a SLA with your current web hosting company, don’t you?

Not sure?

Or was your reaction simply, “What’s a SLA?”

That’s not surprising, the first time many customers hear about an SLA, or Service Level Agreement is when their web site is down and they’re trying to find out what they can do about it.

Many of those same customers are shocked when they find there is nothing they can do about it because (especially if they are on a minimum year-long contract and no get-out clause) the web host either has no SLA, or the SLA is totally favourable to the web host or the SLA’s “guarantees” are worthless. We’ll be taking a look at those three scenarios in a minute.

If you are responsible for running a company’s commercial website then you should NEVER host your website with a web hosting company that does not have an SLA.

As a webmaster your mantra should be: No SLA - no deal!

(If you want to see a Service Level Agreement here’s ours as an example. You may want to compare it to that of your hosting company).

Typically, the SLA will include a network uptime or availability figure. This is where you may wish to get a big pinch of salt ready with the figures fed to you by some companies. When looking at a SLA ask yourself:

  • is the figure independently monitored - can you see the results?
  • is it guaranteed (see “when is a guarantee not a guarantee”)
  • what is the actual figure - the difference between 99.99% and 99% is over 86 hours, or over three and a half days - which extra three days do you want to have no website availability, God forbid it should be during the Xmas sales!
  • what are the exclusions used when calculating the uptime figure? - normally, this will include both items that are beyond the power of the host to prevent, such as denial of service attacks on a server, and things such as routine maintenance - the network isn’t considered “down” just because a well-run hosting company undertakes necessary maintenance to your server.

You may be familiar with the uptime figure, it’s used as a hook by most hosting companies to get you to sign up with them - the figure is usually 99% or above - but for many hosting companies the figure is worthless. That uptime figure needs to be in the Service Level Agreement, backed by a money-back guarantee or you are being short-changed - literally.

Firstly, you have the companies that have no SLA, often the excuse used is that it is a “budget” web hosting account that costs so little that they can’t afford to give uptime guarantees. Then why don’t they say that instead of splashing “99.9% uptime” all over the sign-up page? If they have so little confidence in their product that they won’t offer ANY guarantee, say even 80%, then just how bad is their service. AVOID!

Then there’s the companies with an SLA, but they have no actual way of being able to justify that figure they used. Often these are affiliates or resellers of another company’s hosting and they have no access to the actual uptime figures nor influence over the uptime. They are consumers of someone else’s products just like you, but slightly higher up the food chain.

What if you can show that the actual availability of your server was less than the headline uptime figure used by your web host? Disappointingly, that’s when many people find out that a guarantee isn’t always a guarantee!

Unless the web host offers a guarantee that includes money-back in the event of their failure to live up to their promises (e.g. uptime) then it is not a guarantee - because they don’t have to give you anything back in the event that their service falls below the level they promised! They suffer no penalty for failing to fulfill their specious “guarantee”.

Those of us with a legal background know that there are ways to make companies live up to promises but let’s be honest do you really want to have to go to Trading Standards, the Better Business Bureau or the County Court to extract compensation every time your website is down?

Wouldn’t life be easier if you just hosted your commercial (or personal) website with a company that excelled at keeping it servers running year-after-year, and that provided you with written details of the refunds that you would receive in the, highly unlikely, event that they didn’t do exactly as they promised?

Needless to say, here at Intrahost, even our “Value” entry-level, £4.95 pm, shared web-hosting account is backed by a written, money-back guarantee, in our Service Level Agreement.

Your next step is to check that you have a SLA with your current host - if not - MOVE!

If you have an SLA read it carefully, you’re looking for a guarantee of uptime, with reasonable exclusions (stuff that the host can’t really do anything about), and a clear and specific refund amount for each hour your site/server is down; and a reasonably easy way of proving and claiming for, that downtime. If any of those features are missing it is time to seek another more responsible web hosting company.

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

by: Chris Hudson

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?
