Nous observons des pertes de paquets sur les acces. Nous cherchons l'origine du probleme.

we will hard clear the bgp session between routers, small IP outage will be expected for few seconds.

We found a physical problem with an optical module on th2-dsl3-a1, this port been shut, and another one belongs to the same port-channel took the charge, so the problem is eliminated.
We'll be replacing the defected module shortly.

Nous avons coupe un liens avec des CRC.
Le port a commence les CRC en meme temps que l'intervention
qui a eu lieu le 3/01 à minuit, mais les problemes sont completements decorrele.
C'est ce qui nous a fait perdre du temps sur la resolution du probleme.

We will undo the rollback at 6:00 tomorrow, since its not related to the packet-loss mentioned earlier.
