Hey again
Aye, I've tried all the simple things and this problem occurs for every user who's ISP is NTL (well, those in the same district anyway). When I do a traceroute on the domain from a foreign server, the IP returned is: 217.204.47.98 which isn't the same as that returned by that DNS request. :S
Paul M: seems to be the case. I can't connect to my pop3 server either. Basically, no matter what the subdomain of sonicunion.co.uk i try, it always attempts to connect to the old server. I've set up sonicunion.uni.cc so people can go to the site but I still have no way to send/receive emails or telnet my server.
