Is anyone here in the UK and having mobile phone signal problems on o2? O2 network has been down for me for the past 3 days, no signal at all.

First their message was that their network was busy, now it's showing a 'problem with the local mast'.

Nothing directly from o2 to explain what's going on or how long this is going to last. Many messages on Twitter asking WTF is going on with their service all over the country.

Other networks that rely on o2 as their backbone are also having service status problems too.

I can't seem to access the UK bread for some reason so have had to post this here..
