With Sainsburys website going down this week and Amazon’s the weekÂ before it is worth taking a moment or two to consider what would happen to your business if your website was out of action.
For most e-commerce clients this could have catastrophic consequences: not only would sales evaporate but you would also lose access to all your salesÂ and customer data.
However, hosting and the quality thereof is often totally ignored in client briefs.Â It is definitely not a priority and is only ever occasionally paid lip service.Â This may have been ok a few years ago when websites were just an experiment and an addition to an existing business rather than the core to a business.
However, it is difficult to convince people to invest in proper corporate hosting as there is aÂ perception that hosting should be practically free. It’sÂ true there areÂ some companies offering hosting for Â£10 per year of less.Â Honestly, what do you think theseÂ companies would provide in terms of back up or reliability servcie lever agreement.Â Not much I think.
So what should you consider when hosting your website.Â Â There are many things to consider, here are just three.
First, where is your website being hosted and who manages and owns the servers.Â Most websites in the UK are hosted in Telehouse in Docklands where there are massive generally well managed datacenters.Â But have you ever seen inside a data center, have you ever asked about their air conditioning systems, their own back up power supply, their connectivity to the web?Â Then what about the servers; who owns them? Who is responsible for updating them with critical patches? When is this done?Â What happens if they crash? What is the rebuild time? How many other sites are their on the same server as yours? How secure is the access to the servers?Â If you are not asking these questions then you are not taking your website presence seriously.
Second there are back ups.Â How often is your site backed up and where are the back upsÂ kept? If your service provider’s data center is blown up (a very realistic proposition, especially if you house your website in Telehouse in docklands) will the back ups go up with it.Â Â If they are kept offsite how often are they taken offsite.
Third, what aboutÂ redundancy.Â Â If your server crashes is there a mirror server which will automatically take over?Â What if your website is overloaded with visitors, can your server handle the traffic?Â Is there a load balancing mechanism that will automatically divert users to an alternative server?
All these issues need to be addressed when considering hosting and website owners need to change their mindset from considering hosting as essentially a free service to one that is valued and is invested in appropriately according to business requirements and risk assessment.

Disclaimers and signatures in general are very easy and quick to implement. Saying that if you are a small business running exchange 5.5 2000/2003/2007 and need to ensure that all users are setup with a standard Disclaimer and Signature or other advanced features you would normally need to use a third party software.
There is no better product than Exclaimer to achieve the desired results. In the Scenario where a client with over 50 users needed to add a disclaimer, Signature and auto-reply (to certain groups) with different responses. My only request to the client was send me a list of all user details and request all users to remove signatures before they leave at the end of the day.
An hour later after updating there Active Directory with staff details I was able to setup a centralised location for all Signatures and Disclaimers.
All user’s information is pulled in automatically from the active directory, and groups where setup with different auto-responses.
Just how popular is Vista today? How many people have switched from IE6 to IE7? Just what share of the browser market does Firefox have?
For answers to these questions and more it is worth regularly checking W3 Counter’s Global Stats which can be found here:
These stats are generated by tracking the last 32 million unique visits to 5,500 websites that represent a broad cross section of internet traffic. From each unique visit, the web browser, operating system, country of origin and screen resolution can all be determined to produce a reasonably good picture of just what general web traffic looks like today.
From looking at the latest stats for 20/08/07 we can see that a person in the USA, running Windows XP, Internet Explorer 6 with a screen resolution of 1024×768 is your average Joe web surfer, this accounts for 6% of web users. Myself I am based in the UK, running Windows XP, Internet Explorer 7 (as my primary browser) and screen resolution of 1280×1024. Only one in a thousand computers run the same combination as I do.
But lets look at the really interesting stats.
Starting with web browsers we can see that Microsoft’s Internet Explorer still dominates the market with an approx 66% share. This is not taking into account the stats for IE5, IE4 and earlier, which I am sure some systems in less developed countries are still running. However the real story here is that IE’s lead is slipping due to Firefox’s continuing popularity – Firefox versions 1.0, 1.5 and 2.0 now account for approx 25% of all web browsers. Safari still has an approximate 2-3% share, however it is unclear whether Safari or Firefox dominate the browser industry for Macs.
Operating system stats show that it’s been a slow start for the brand new operating system from Microsoft – Windows Vista. Just 3.33% of the OS market in August, but recent trends show that share increasing. In May 2007 it was 2.13% and has increased by 1.2% over the past 3 months. XP still dominates, but I expect to see Vista’s share increase more rapidly over the next few years as more people buy new PCs or upgrade. Mac OS X users still account for just under 4% of all users suggesting that the marketing managers at Apple need to do more than their latest “Mac vs PC” advertising campaign to encourage more people to make the big switch.
The stats for the countries of origin offer no real suprises with the US of A leading. Germany and the UK in 2nd and 3rd place respectively and a suprising Latvia in 4th. The Chinese account for just over 2% of all users who visited the web pages in question, but recent media reports suggest this statistic is far higher (almost as dominant as the US). It is well known that the Chinese government have blocked internet sites, which could include many in these reports, or that it may be that the sites in the report are more westernised, located in the US (may be blocked), or are written in languages that Chinese web users are generally unlikely to understand – you can only speculate.
Screen resolution statistics are largely trivial, but the most common is 1024×768, which I am sure will remain dominant for many years to come. Many IT professionals, gamers and experienced computer users generally opt for higher resolutions such as 1280×1024, or widescreen resolutions such as 1280×800 or 1440×900. If any of these statistics should be taken into consideration its that 8.42% of web users are still using a low resolution of 800×600. This figure is falling slowly, in May 2007 it was 9%. While many of the systems running 800×600 may be in less developed countries, nevertheless it is important for web designers to design websites with this low resolution in mind. An example of how not to do it – http://www.hrodc.com/.
Because of the lack of legacy data, it is difficult to put some of these stats into context over the past few years, but rest assured I will be keeping track of them over time and a review of the stats will come in the shape of another blog article towards the end of the year.

One of the most common questions I get asked from clients is, why do I get spam or email virus that appears to originate from inside our organization.Spammers and Viruses are becoming evermore resourceful in trying to elude us to open their emails. One of the simplest ways of getting you to open an email is spoofing email address of users we trust. There are several ways they can get hold of userâ€™s emails the question is how you stop spammers and viruses from faking addresses.Today’s anti-spam are composed of several layers for detecting spam. One of the methods for detecting fake or spoof emails is inbound authentication and Identity verification technically known as SIDF.
How Sender ID Works
- The sender sends an e-mail message.
- The recipientâ€™s inbound e-mail server receives the message.
- The inbound e-mail server checks which domain claims to have sent the message and checks
the DNS for the SPF record of that domain. The inbound server then determines if the IP address
of the sending e-mail server matches the IP addresses that are published in the SPF record.
E-mail messages that fail may be deleted, blocked, or sent to the Junk e-mail folder.
- As a recommended option, the Sender ID result can be combined with reputation data about the
IP/domain holder. This reputation data enhances delivery decisions for all e-mail, including
messages sent from both legitimate senders and spammers which may pass the Sender ID check.
- When combined with the receiving networkâ€™s anti-spam and anti-phishing technologies, the
e-mail may be delivered to the Inbox, the Junk or Quarantine folders, or may be blocked and deleted.Â
Question is, so why are fake emails still getting through?
Many small businesses do not know or still have not implemented this extra layer of security until a majority of business implement the SPF on their domains we will still continue to receive fake emails or we could opt to block all emails that have not implemented, thisÂ solution is risky as businesses could possibly lose important emails from potential clients.
