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

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.

Dual-SIM, or domestic roaming, for applications such as this are a bit
of a challenge. Normally what users are looking for is redundancy if one
or two masts fail, not if the whole network fails.

Its a reasonably important service so having dual sims should really have
been in the design. Ditto down at gatwick where - inexplicably - they dumped
a wired link from the control tower for a phone network data link to power
their information screens. Which then went down recently. Whatever shiny
suited salesmen sold them that pup was probably laughing all the way to the
wine bar after that.
