O2 network BACK UP and running after 24hr service BLACKOUT

The issue has left many customers inconvenienced.

The Swedish equipment maker, which manufactures much of the backend gear in the world's cellular networks, said today the outage was down to an expired certificate in an earlier version of its management software that was in use by a number of European telcos. Work is now ongoing to fix the fault and customers are being encouraged to use wi-fi where possible.

O2 said that services are slowly being restored and the company would continue to work on the problem throughout the night.

The company confirmed the network issues on their website, saying: "Our technical teams are investigating reports of issues when using data".

Around 32 million people are seeing lost in data services after the O2 network suffered a disruption to service.

"The faulty software that has caused these issues is being decommissioned and we apologize not only to our customers but also to their customers", Ekholm said.

It comes as O2, Tesco Mobile and Sky Mobile customers across the United Kingdom experience problems with mobile data services.

The outage was "caused by Ericsson-made software errors related to its packet switches, covering our customers nationwide", SoftBank explained. The machines have been covered up until the issue is fixed.

An additional seven million customers of Sky, Tesco, Giffgaff, and Lycamobile, which O2 provides services for, are also impacted.

Computing will update this story as soon more news comes in.

The fragility of the increasingly connected systems that keep modern, Western nations running was underlined Thursday when major telecoms network O2 ceased to transmit mobile data from around 0530 GMT.

The company said it would be closely monitoring data services over the coming days and promised to carry out a review to understand what went wrong.
