O2 again showed its commitment to mission-critical wireless by dropping the national data network on Saturday, another unexplained outage that left customers having to talk to each other again.

The statement we finally managed to get out of O2 this morning simply admits that there was an outage, and that it lasted for around two hours on Saturday, though the O2 forums, and reports from El Reg readers, would seem to indicate a longer downtime.

Given the operator's reluctance to explain what went wrong last time, we can only assume that whatever it was still isn't fixed. We'll continue to ask how O2 is going to reassure customers that its data network can be relied upon, when outages are not only commonplace, but also unexplained. ®
