The first large hop (212.250.14.62) appears to belong to NTL (according to Neotrace).
Looks like a problem they need to deal with.
I've contacted EV1 servers and they are looking into it from their end as well, but I think the problem is with NTL and not them.
Tons of sites are affected - Newshosting/Filefront/Newsreader and anything hosted at EV1
