A special message from MSN:

While Christmas is a time of joy for most of us, that's not the case for the UK's most vulnerable children and young people. We've partnered with giving platform Benevity to raise funds for two charities - the NSPCC and The Children's Society – to try to help change that. You can help make a difference - please donate now.

O2's data network will be back online by tomorrow morning, its parent company has finally announced.

The announcement finally brings a close to mass confusion as O2 customers tried to work out why their 4G connections refused to work.

But it means that they will have been without internet for more than a day, after the internet broke early this morning.

Until now, all companies involved would only say that they were fixing the problem as soon as possible, and that they were working hard on bringing an end to the issues.

Now the two companies say they are "aiming" to have the problems fixed by Friday morning, after having identified the problem that led to the outage.

The issue appears to have been with a piece of software, provided by Ericsson, which is relied on not just by O2 but by other companies that experienced problems, such as Japan's Softbank.

Börje Ekholm, president and chief executive of Ericsson, said: “The faulty software that has caused these issues is being decommissioned and we apologize not only to our customers but also to their customers. We work hard to ensure that our customers can limit the impact and restore their services as soon as possible.”

The company said most of its affected customers had got back online, but that some – presumably including Tesco – were still not working, and that it was continuing to work with them.

The problems have hit as many as 30 million people in the UK, affecting not only O2 customers but users of the networks that borrow their infrastructure, such as Tesco Mobile and GiffGaff.

It also hit transport networks and other systems that rely on O2's internet connections to transfer data.
