Soham (CB7) Lots of pixellation and several 'No Signal' events on Ch4 between 21:00 and 22:00 (The IT Crowd - only saw 1/2 of it). Seemed to be worst on the ITV/Ch4/Ch5 multiplex, BBC seemed better.
Had some pixellation over the last few weeks, previously rock solid, completely useless tonight!

In Peterborough PE3. All this week our TV has been virtually unwatchable with either pixilation on most channels but more often on BBC and/or complete loss of signal.
In 6 years we have only had this problem once before just for one day.
