O2 restores network after outage

Mobile operator O2 has fixed network problems that left hundreds of thousands of customers without voice and data connections for around 24 hours.

“Following previous updates, our tests now show that all our 2G and 3G services have been fully restored for affected customers,” the company said in a statement.

“If any customers are still having problems we recommend they turn their phone off and on again. Once again, we are sorry.”

The problem lay with one of its network systems, which was having difficulty registering mobile numbers on the network, O2 told CIO UK sister title, Computerworld UK.

O2 customers began experiencing problems with their voice and data services on Wednesday afternoon. Subscribers to GiffGaff and Tesco Mobile, which piggyback onto O2’s network were also affected.

Some industry commentators have suggested that the service failure could have long-term repercussions for the company.

“To have an entire network down is a poor show for the company, and does not bode well for an operator who plans to deliver 4G services in a year’s time,” said Askar Sheibani, CEO of IT and telecoms repair company Comtek.
