Ok that answers some questions thanks.
For those who wonder what Akamai is....
Basically they have a large number of servers round the world. When you request information from one of their clients Akamai look where you are based and route you to the server nearest/has the best connection to you.
Therefore if you are based in (say) Scotland and make a request from gov.uk Akamai will look and see you have a strong connection to their servers in Holland and server the information from there.
Although the host data is stored in the UK it is mirrored around the world.
Akamai may be a familiar name if you have ever download Adobe Acrobat. Their software is packaged with that (and other software). It "helpfully" turns your PC into a peer to peer node so that if you have content on your computer (normally large files or images) relating to one of their clients, when it is requested by someone online Akamai can use your PC to serve the image....
Your thoughts on this may vary but you gave permission for this to happen when you clicked the T&C box without reading it... (one reason for using Foxit reader instead). Some security sites consider the peer to peer element naughty and give removal instructions some don't.
As far as I've seen on the Gov.uk site nothing there would be part of the peer-to-peer program.
So basically the site is hosted by a UK company, in the UK, but mirrored and distributed worldwide by a US company....
