Date: 2018-08-30 06:59:18 UTC We found a faulty interface was causing the CRC. A new one has been used and the link is now up and clean at 100Gbps.
Date: 2018-08-30 03:07:10 UTC It will take some time before being able to change fiber. We will proceed within the next few hours.

Date: 2018-08-30 00:26:38 UTC We run into a total isolation of B side because of an error of the port removal. All traffic has been re-routed but some latency/loss can be seen few seconds. The port is back online and we continue the procedure.
