Just Noticed my phone is SOS only on Vodafone, (Yeovil)
There seems to be reports on Twitter about a major failure across various parts of the country not just Yeovil! Must be a single point of failure somewhere.
Yeovil Vodafone Shop Message about 28th Feb 2011 outage
Vodafone Press release:-

A breakin in one location can bring down most users in the South of England,
sounds a bit suspicious to me, where is their disaster plan and failover recover system?
