At 15:40 CEST a darkfiber between NZS (Nedzone Steenbergen) and EQX-AM7 (Equinix AM7) went down, carrying 200 Gbps traffic.

Currently all traffic is sent over the alternative path on our ring namely NZS - GSA.

We have contacted the darkfiber provider Eurofiber and are currently awaiting an exact issue description.

Update 19:20 CEST:
The issue in this case is a fiber break because of digging in the area, the break location has been found and engineers are currently on their way to the break location to asses and repair the broken fiber duct.

Update 2019-07-03 0:05 CEST:
The fiber has been repaired by our darkfiber provider and the darkfiber has been returned to full operation. At this time Nedzone is fully redundant again.

At 23:12 we received notification of the connection towards GSA (Global Switch Amsterdam) as well as in-house patch connections going down. After inspection we noticed this issue appears to be an in house issue at Nedzone.

At 23:54, we received notification the connection gone up again.

Currently we are still awaiting more information from Nedzone about the issue.

Update 28-04-2019 4:39:

#796 Packetloss / networkloss DBC

Posted: 2019-04-25 16:51

Start: 2019-04-25 15:25:00
End : 2019-04-25 16:17:00

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.
