Reply to comment by LocoCoyote in Lufthansa Passengers Are Stranded Because of a Severe Tech Outage | Airline passengers on 177 flights were impacted when a construction company accidentally cut fiber optic cables, effectively shutting down the airport by Hrmbee

That's exactly what I thought. Redundant systems and everything but sometimes it hits the one place they're vulnerable - where both cables run in one trench

Yeah, if they're in the same trench/conduit then that certainly presents additional challenges. For sites that are subject to frequent construction and/or maintenance activities such as airports, it would be prudent to have at least one backup that is using a different physical route. In some facilities that I'm familiar with, they've gone with wireless systems (microwave, satellite, etc) as a backup in case the physical link goes down.
