O2 4G network down across the UK

Ericsson says an expired software certificate was responsible for the outage that left tens of millions in the United Kingdom unable to call or text from their mobile phones on Thursday.

Local O2 customers have also reported issues, with many people in Dundee left unable to use data or make calls.

An O2 spokesperson confirmed the problems, saying: "Our technical teams are investigating reports of issues when using data".

"One of our third party suppliers has identified a global software issue in their system which has impacted us", it said.

It said: "This allowed hundreds of people from both our technical teams and our third-party supplier's teams to focus on fixing the problem, helping us to restore data services as quickly as we can which will also help reduce the high network demand we're now seeing for voice calls". It also affected services that use O2's network, bringing down digital timetables at London bus stops... They're now working hard to resolve the issue so we would imagine it won't be too long before its back up.

Chance of rain mixing with snow later today
Temperatures will be colder today than yesterday, with highs in the 30s and low 40s, and wind chills in the 20s and low 30s. There may be lulls at night while becoming steadier overnight and continuing into Sunday before exiting mid-late afternoon.

The company has 25 million customers across the United Kingdom.

"We apologise for any inconvenience", the firm said, after problems were first reported at around 5.30am.

O2 said that services are slowly being restored and the company would continue to work on the problem throughout the night. "Our technical teams are working extremely hard to resolve this", the company said. Work is now ongoing to fix the fault and customers are being encouraged to use wi-fi where possible.

The network outage isn't just forcing British mobile users to put down their phones and talk to one another.
