O2 data network back to normal

Full service to O2’s data network has been restored after an air conditioning failure saw parts of the country without a connection yesterday evening

O2’s data network is again fully functional after an intermittent fault saw parts of the country without a data connection for up to eight hours yesterday. O2’s data network went down yesterday afternoon after an air conditioning failure in one of its London sites caused the technology which carries its network data to overheat and break down.

Data services were restored in London, O2’s biggest area for data consumption, by 9:30pm yesterday evening. O2 said all problems were resolved by 1am this morning. An O2 spokesperson said: "An air conditioning failure in one of our London sites caused two nodes which carry network data to overheat yesterday.

"This resulted in intermittent data access for customers in some parts of the UK. Full service was restored by 1am today. We apologise to our customers for the loss of service."
