One of the 2 office routers had a hardware failure. I have an OIT ticket open. No ETA on resolution yet.

Down BGP sessions disabled on our side until the remote side is fixed.

Mentioned in SAL (#wikimedia-operations) [2020-02-24T12:05:28Z] <XioNoX> re-enable deactivated BGP sessions from ulsfo to office - T239893
