Expected downtime is for 1 link and mere minutes at most. Some of the time is taken by reloading BGP routing time.
Connectivity will likely not drop, but there will be flip flop on routes and most likely some congestion for this few minutes period.

Let's hope there isn't any issues and this is actually accomplished in the mere minutes.

One fiber has to be migrated to another route due to another DC doing renovations & maintenance, rebuilding their DC.
