"Tracker systems which rely on the O2 network have also been affected by
the outage, meaning countdown screens at London bus stops have stopped

Screens which normally display the predicted arrival time of buses
across the capital are now blank.

A TfL spokesperson said: "We're sorry that customers are unable to use
our Countdown screens at bus stops for live travel information.

This is a result of a nationwide O2 data outage. We are working with our
service provider to resolve this as soon as possible."

ps Actually, it's more likely that O2 working with *its* provider
[Ericsson] will get this thing resolved.

Obviously a backup link wasn't in the spec. Nice one TfL.
