Default Looking forward to when even more transport, and self drivingcars, rely on 24x7 data connectivity

"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


I'm not convinced it is. While it's very nice to know when the next bus
is along the vast majority of London bus routes are frequent enough that
you can just wait for a while for the next to turn up.
