O2 mobile data service crashes again

O2 is having serious problems with its data network

O2's data network appears to be suffering further problems, after many users complained of being unable to access any data services from their mobile device. The connection seems to work, but all web page requests time out before loading.

The extent of the problem is still unclear, but it appears to affect all types of data subscriber across the UK, including iPhone users, and it seems that O2 has yet to locate the source of the outage.

"We are aware of a problem with our data network this morning, which is impacting internet services for some customers," said an O2 spokeswoman. "We are working to identify the cause of the problem and restore service as soon as possible."

This is the third time in three weeks that the mobile operator has suffered data outages, which it originally blamed on its IP address allocation system.

The company acknowledged the problem on micro-blogging site Twitter, posting an update stating: "We're having a problem with our data network which will affect data services for some customers. We are working to fix this ASAP."

UPDATE at 1pm GMT: O2 appears to have finally rectified the problems, around four hours after they were first noted.
