End : 2019-10-10 12:49:00

Affects: Traffic Nedzone

At 12:40 we noticed issues (packetloss) with communication between the routers and ring switches causing ebgp sessions to drop.

The issue seems to be with packets that were send/partially balanced over additional unused (disabled) ports, reset of the bridges on the ring-switches resolved the packetloss, BGP sessions are being re-established automatically.

As preventive measure NOC engineers will activate the currently unused (disabled) ports within the next 3 hours.

During the reload times, all traffic is redirected to the other datacenter and transit providers.

If you do not have a redundant BGP session, or have internet connectivity/transit at this location, you may notice full downtime during the reload.

Update 3 October 2019, 6:30 AM:
The maintenance is cancelled as it had no effect on Global Switch Amsterdam router.
However during the maintenance on Global Switch Amsterdam router, we did found the cruelpit on the AMSIX routeservers. Currently it is no longer present and the full routes are being send without any problems.

Update 4 October 2019, 8:30 AM:
The maintenance for AM7 is dropped as the issue was not resolved by reloading the router, but a conflicting peer on the AMSIX routeservers.

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.
