NTL's DNS servers are playing up big style - first noticed Thursday morning.
They are basically returning the wrong IP for any given host for a period of a few hours; after which it reverts back to the correct IP. It is not zone specific; so whilst www.yourdomain.com might resolve correctly; ftp.yourdomain.com could be completely wrong.
This is also affecting customers web browsing as NTL's transparent proxy network relies on their own DNS.
