Orange network issue in Berks?

I'm in Berkshire, in he Egham/Ascot area and for the past 12 hours I
have not been able to make or receive calls - my blackberry pearl just
drops the call during setup, or, when I call the phone, I go straight
to answerphone or get a network busy error.

After 45 minutes queuing to get through to CS I thought I'd see if
anyone else is having a similar problem.

TIA

James
