Possibly when a protect path starts being used.
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. -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, US | | Making life hard for others since 1977.
