   > When it went to flip into the backup, we discovered that the backup fiber had a break

   Pretty grim that a life critical system wasn't designed to report that the backup fibre was unserviceable until they attempted to switch over to it.

   I wonder how long it was down? Days, weeks, months?

      Sometimes your multiple fiber paths end up in the same bundle, severed by the same backhoe. It's always a fun day when that becomes apparent.

         If you design your network badly sure. Spend 3 months with BR once trying to get diverse routing out of one location to their two nearby exchanges, took a long time for them to work out what they needed to do as they had the two paths crossing in a single location for quite some time, but eventually they sorted it.

            Bad design is the default - it takes hard work to have real redundancy, and if no one checks/demands it? Luck of the draw, or worse.
