Affects: Connectivity DBC

At 15:25 we got warning alerts from our monitoring system that packetloss was noticed on multiple switches throughout the network in DBC.

After debugging we traced this back to one of the linecards in one of the coreswitches, as all ports on this card are setup redundantly we have rebooted this linecard.

After it went back online we first tested with a small number of racks to check the stability before enabling all the ports.

At this moment all ports have been enabled and stability has been resumed, we will keep monitoring this linecard and if the same issue occurs we will replace the linecard in question.
