   > 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.

         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

            lol there’s supposed to be …. But then greed gets in the way lol.

            Usually it’s a combo of a tier 1 that decides that a resell agreement is “good enough” and “well just eat the loss” and then by the time stuff like this rolls around “we’ll get back to you” + a bunch of silly explanations that boil down to “you’re not gonna sue us though” start coming out lol
