Just before 8pm last night (11/05/10), mobile phone network O2 suffered a voice and data network outage which left many customers annoyed. Many contract business mobile customers had no voice or data network whilst pay-as-you-go customers didn’t seem to suffer.

An internet update on Twitter by O2 said this, “There’s an issue affecting our service in some of the UK. Sorry – our engineers are investigating and we’ll update you when we can.” What services and what areas of the UK were not expounded upon and customers were annoyed that the O2 site was not too helpful. Luckily for business mobile customers, the O2 network seems to be back to normal this morning.
