So it looks like the Slow lines are reopening for the time being...
There are many UPSs and backup generators around the network, but equipment failures like this can require far more diagnostics than just "the power's off so we'll switch in something else". If that had worked, even on the second or third goes, we wouldn't have had the problems up until now.
As has been posted above, often switching or cabling is more vulnerable as a single point of failure.
Why does the signalling power supply in the area not have UPS?
