O2 is racing to restore mobile coverage in parts of London, Kent and East Sussex, after theft and vandalism hit an East London operations site.
The mobile network operator put up a service message at 12:50am on Tuesday, reading: "We've got a problem that means you can't make calls, use the internet, or send/get texts and emails in parts of East London, North London, east Sussex and Kent." The message was still up around 12 hours later, at the time of writing.
"We continue working hard to address the issue affecting services in parts of North and East London, Kent and East Sussex," O2 said in a statement shortly after midday. "This was caused by theft and vandalism at one of our operations sites in East London. We sincerely apologise to affected customers and will update progress regularly."
The mobile virtual network operator (MVNO) Giffgaff, which uses O2's network to provide its services, has maps on its forum detailing the extent of the 2G and 3G outages.
