Not just Birmingham
In Reading we've had problems for nearly 2 weeks. No broadband connection for days (sometimes it's only hours) then the connection will come back for a few hours - and when it does, some times it's really slow (0.1Mb - 4Mb) and sometimes I get nearer to 50Mb than I've ever had - but then it goes again.
Had no connection for most of yesterday, it's back again this morning.
