Yep, for two or three operators. This time it was a national outage but seemed not to last more than an hour.
Last time it was an over-zealous upgrade that wasn't ready. I guess it still isn't....

Didn't the same thing happen less than a fortnight ago?

Cancellations to services on all routes
Due to a fault with the signalling system trains have to run at reduced speed.
Train services running across the whole Great Western Railway network may be cancelled or delayed. Disruption is expected until 15:00 19/05.
