A decade or so later, the arguments still go on but now with a variety of potential locations to host from in the UK; it has now changed from a country-specific requirement to a city-specific requirement.
It is no secret that 95% of all UK internet traffic flows through the Telehouse North and Telehouse East datacentres in London so a lot of companies seem intent on hosting there.
In truth, there isn’t all that much difference to the typical UK web user – an ADSL connection will introduce an average latency of 20 to 30 milliseconds and hosting content at one of the larger datacentres will usually incur an additional 3 to 5 milliseconds latency per page request.
The flip-side to the coin of course is that if your website caters to a multi-national audience such as both the UK and the USA; where should you host the site ?
In cases like this, a CDN (Content Delivery Network) can be a cost-effective way of getting around this issue; items such as Flash assets (.swf) and images can be retrieved from a server which is geographically closer to the user connecting to it.
