Web hosting, service availability and security
Your web site is located on a computer running a piece of software called a Web Server. How well the hosting works is important to your web site. It needs to be fast and reliable. That’s what we aim for.
If you look around at what’s available you’ll find web hosting prices ranging from free to tens of thousands. Every hosting service offers different features. In simple terms: the more you pay the more and better you get. You don’t want the worst and you can’t afford the most costly. You want that which offers the best fit to your needs. It’s like buying a car, the little 2 seater Smart car is totally impractical for most of us, we need to carry more passengers and luggage. A nice new Bentley addresses those needs but with levels of luxury and engineering resulting in a price a little beyond my budget. The majority of new cars sold are family saloons with room for all the family and their luggage at a more realistic cost. The family saloon category still covers a range of features and prices, perhaps you need a 7 seater. Web hosting too is not “one size fits all”, some web sites need extra features not needed by most and that may have an impact on cost. There’s a substantial list of features available, you only need those relevant to your circumstances. It can be difficult to choose without an understanding of what each means in practical terms – and unfortunate if you sign up to a deal that omits a technical feature important to your web site.
As a hosting provider it’s difficult too: how do they explain what amount to dozens of technical features?
Our answer is to use our expertise to identify which bundle of features delivers the benefits each web-site owner needs. Fundamentally those are speed and reliability but there are technical aspects like database services, software and computer languages (and versions) available, backup policies.
We no longer operate our own servers but buy services from specialists. That gives us the flexibility to change providers as the various offerings evolve and to use specialist providers where that is the best way to address your needs.
Saying “trust us to make the best choice for your needs” is all very well but if you’re new to our services how can we ask you to trust our judgement? So I will explain some of the key features we provide:
- Solid State Disk (SSD) storage. That means your web site is stored on silicon chip memory instead of mechanical Hard Disk Drives (HDD). The benefit is speed, your web pages are faster to load. SSD is typically 4 to 10 times the speed of HDD. SSD is more expensive but uses less power and, with no moving parts, is more reliable.
- Fast internet connection. Just as home broadband connections range from under 1 Mbit/sec to as much as 1000 Mbit/sec, so do web server connections. Home users on slow broadband will complain of TV shows “buffering” (pausing to await more data). A similar problem arises if your web host’s internet connection is too slow. The benefit of a fast internet connection to the server is speed, your web pages will load faster.
- Generous bandwidth provision. Bandwidth is a measure of the amount of internet data your web site sends, it is relatively costly, every time anyone accesses your website they use some of that bandwidth. Mobile phone packages come with a bandwidth allocation for accessing web pages over the phone network, that allocation can be quite small and if you exceed the limit it can become costly. A similar constraint applies to web hosting, even those offering “unlimited bandwidth” have a small-print condition of “subject to fair usage” and/or will apply throttling to slow down access to your web site and so reduce network usage. We aim to provide at least twice as much bandwidth as we expect you to need (but also when creating a web site we aim to minimise the bandwidth requirement).
- Generous disk-storage provision. We aim for disk capacity of double your actual need. As you may have found on your own computers, performance can drop as disk usage gets over about 80%. There are hosting packages that promise unlimited disk storage, that’s just marketing, what they mean is “more than adequate for most users”.
- Backups. Most hosting services provide backups. This is for reliability. Things can break, people can accidentally delete something important. You need daily backups, storage of (a limited number of) past backups, “on-demand” backups and free restoration of backups on demand.
- Software: This topic is much more complicated, there are thousands of choices. At a detail level you may not know what you need until you find your chosen host doesn’t provide it. We address that problem by building web sites knowing what software is available. Where a less-common requirement arises we will use specialist hosting.
- Use of a Content Delivery Network (CDN). A CDN keeps copies of your web site on servers distributed all over the world. The benefits of that are speed and reliability
- reliability: if your primary server has a problem, the CDN will continue to provide a service
- speed: users on the other side of the globe may get your web pages faster than having to communicate round the globe (by fetching your web site from a web server closer to their location)
- speed: if there is congestion on the internet between a web site visitor and your primary server, pages will be fetched from a more distant server if that will deliver them faster.
The chart below shows access speeds from various points around the world to a UK hosted web site when a CDN is not in use: from Europe the home page loads in a fifth of a second, from Australia it takes ten times as long. One purpose of a CDN is to make remote access faster.
- We want the web sites we deliver to be available 24 hours a day, 365 days a year. We all have experience of problems with computers and web servers can fail. That’s why we implement processes and features to manage the risk.
- Service monitoring – the sites are automatically accessed from different computers once an hour. If there’s no response we get an alert and can investigate.
- CDN – the CDN replicates your site to different global servers such that if there is a failure visitors should see a copy of the site from one of those servers.
- Backups – in the event of a catastrophic problem it should be possible to restore your web site from a recent backup. We also keep an older copy of the site on a separate computer. That means if your site has been subject to a delayed action hacker attack (the delay means the daily backups have been affected before the attack takes effect and so harder to recover) we can still restore a working version but it might need some updates.
- Separation of services – we intentionally avoid holding the domain name at the host. That means that in the event of a catastrophic failure we can route the name to a different host.
If you wish there is more we can do but charges apply and we regard this as only necessary for the most business critical sites:
- Provide you with a separate backup copy
- Implement an additional backup process, maybe once a week to a remote computer and retain a longer change history.
- Increase the uptime monitoring frequency from once an hour to every 15 minutes (every minute if necessary but that becomes very costly).
- In addition to uptime monitoring we can implement content image monitoring. In the event that a hacker gains access and corrupts your home page, we can detect the change and raise an alert.
We take your security very seriously, that will be undermined if you don’t do the same. I’m sure I don’t need to repeat all the advice about password security (there’s plenty of advice around the internet like this), I will just add: do make use of 2FA (Two Factor Authentication) and store your login credentials in a password vault like KeePass or LastPass.
