Help re: google error

[nightfever]

When I try to access google, igoogle or gmail, I get an error:

Safari said:

The requested URL could not be retrieved

While trying to retrieve the URL: http://google.co.uk/

The following error was encountered:

Unable to determine IP address from host name for google.co.uk
The dnsserver returned:

Server Failure: The name server was unable to process this query.
This means that:

The cache was not able to resolve the hostname presented in the URL.
Check if the address is correct.

I'm assuming its my end (I'm on a university network) but does anyone know how to fix it? Running tiger and safari.

Thanks

Hmm appears to be working fine now. I have no idea why though.
