    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.

        For mission critical stuff like airports I would like to think they're go for a more rigorous methodology than hope for the best on paths
