Oh, I didn't read William's note properly. Indeed there is probably no point contacting KTH until their networking is working again. They'll surely assume the issues are related. Best to see if the problem clears itself up in a couple of days. They do say access will be difficult and intermittent.

I am not having any problems accessing the GMP website via Warwick University. At some time in the past there was a problem similar to what you are describing though. No one on campus could access gmplib.org from a machine with a campus IP address, but it was possible to access it from anywhere el
