spud,
are all sites slow or just certain ones? if its all sites, it could be DNS thats buggered.
You can override DNS if you know IP addresses of sites. e.g.
http://216.239.39.99 is one of googles ip address's
See if that comes up any quicker than hitting google.com
If it does you could try temporarily using someone other than Tiscalis dns
pipex is 158.43.240.3 for example, catch me on MSN (
[email protected]) if you want info on how to make teh change
