Update: O2 suffers major network outage

UK mobile phone network O2 has suffered a catastrophic outage where its customers are unable to make or receive calls. This started on Wednesday afternoon, 11 July.

This issue has been an on-going two-day problem for all mobile phones on the network, affecting both data and text messaging.

O2 posted a message to Twitter recognising the problem at 16:38 yesterday, in a tweet that reads: "There's a problem affecting some customers' mobile service. Engineers are working to restore full service asap."

This was followed by a status update tweeted at 19:23, which read: "Our engineers are continuing their work to fully restore service to customers with network issues as a priority."

A link was included in the first tweet that directs the reader to a web page entitled 'What makes an award-winning network?', whereas the subsequent tweet had a link to follow the O2 status page. That page shows the action being taken by the network to rectify its nationwide outage

{MPU Placeholder}Customers have found that disabling 3G restores some of the services, although this of course drops the signal obtained down to a 2.5 or 2G level.

That said, some O2 customers in our London offices are able to receive calls but are unable to make them, where others cannot send text messages – despite switching off 3G.

ITProPortal will be updating this piece with any new information, as and when it happens.

UPDATE 10:00am 12 July

O2 has updated its network status page, with the following message:

"10:00 We can confirm that our 2G network service has now been restored. Customers who were affected should now be able to make and receive calls.Our 3G service is starting to restore and customers should expect to see a gradual return of data services as the day progresses.Customers affected may wish to try switching their mobile phones off and on as service returns.We are sorry again for the inconvenience this has caused some customers and can provide reassurance that we continue to deploy all possible resources, and will do so until full service is restored."

UPDATE 11:00am 11 July

There has been another update from O2, which reads:

"11:00 Status - Ongoing

Following the previous update that our 2G network service has now been restored, our 3G service has been restoring gradually.

We expect full service to return this afternoon. In the meantime customers who were affected should still be able to make and receive calls (and may wish to try switching their mobile phones off and on as service returns).

We are sorry again for the inconvenience this has caused some customers. We continue to deploy all possible resources, and will do so until full service is restored."

UPDATE 1:30pm 11 July

O2 has restored its network and services, along with updating the status message on its website - with the following message:

"13:30 Status - Ongoing

Following previous updates, our tests now show that all our 2G and 3G services have been fully restored for affected customers.

If any customers are still having problems we recommend they turn their phone off and on again.

Once again, we are sorry."
