#730 Darkfiber outage DBC - EQX-AM7

Affects: Traffic DBC

At 22:35 CET a darkfiber between DBC (Datbarn Capelle) and EQX-AM7 (Equinix AM7) started flapping, carrying 400 Gbps traffic.

Currently all traffic is sent over the alternative path on our ring namely DBC - GSA while we are investigating the cause into this.

While testing what the issue is on the path some packetloss may appear.

Update 01:45:
At 23:30 CET the connections went physically down and haven't come back, we are still investigating to find the root cause of this issue to being able to solve it in getting the link back online.

Update 2018-12-17 15:49:

After a lot of debugging last night and today we noticed one of the amplifiers at DBC giving out a much higher value then what was measured using a power meter, where we would have strong light levels from one side, but not from the other side.

We've replaced the amplifier in question and currently the connection is up and running again, we'll keep monitoring this line for some time.
