We are currently experiencing an issue on one of our dark fiber optical line between Roubaix and Bruxelles on the Roubaix <> Nazareth span.
After a first troubleshooting phase, the issue is confirmed to be related to a degradation of the cable optical parameters. Investigation is ongoing with the cable maintainer.
Impacted circuits have been moved on backup path but may have been impacted by errors between approx. 2:20 and 3:05 CEST.
