O2 data outage

I read that:

"Network operator O2's data network has experienced an outage across the UK.

Internet and multimedia message services have been disrupted for all of the firm's customers who are on monthly contracts.

O2 is not releasing the cause of the outage but says that its engineers are aware of the cause of the problem and are working to correct it.

...

The firm was unable to say when the problem would be fixed. "

Thankfully my main data device is on Vodafone.
