That wouldn't explain why things are *still* down.  The whole idea
behind a protected path is that it's a failover path; primary path goes
down, protected path takes over.  Depending on the medium there's a few
milliseconds of downtime (talking about SONET rings here).  So this
would make me ask: why are things still down?

If a protected path was already in use (re: fibre cut), then that would
make me ask: why hasn't anyone failed back to the primary path?

I'm inclined to think there's a single carrier involved here, and
possibly who lacks redundancy (i.e. both paths are shoved through the
same conduit/fibre bundle which has been cut).  There's no point in
bothering with redundancy if there's a SPoF anywhere within the
topology.

But like everything else, this is all speculation.
