Had problems recently
In the South Watford (herts.) area, last Tuesday I guess. After 24 hours it started connecting again, but only to their registration server, which rejected us since it had no record of us as dial-up subscribers! (yeah, like maybe 8 years ago!).
Also the registration server doesn't support Windows7 RC1 yet either.
Anyway, after a call to the Indian center they reset our modem and account and things are working again.
On the whole I find the service is not bad, though having Indian-based support makes things difficult for people like me who have problems speaking 'Indiaglish'.
ttfn
PH - the Pr0n is flowing again!
