FS#15343 — Gravelines <> London
Incident Report for Network & Infrastructure
Resolved
Between 10:15 and 11:35 PM, one of the Gravelines <> London 100G links was unstable. This is a known bug on optical CPAK Cisco for which we have a software workaround. Cisco is also trying to supply us with a new version on which the optical problems is definitely corrected and whose deployment will start shortly.

Update(s):

Date: 2015-11-10 14:41:01 UTC
The transponder has restarted and we applied the software workaround. The impact is limited to a flap on the circuit.

Date: 2015-11-10 14:40:24 UTC
We will preventively restart a transponder which will impact the second link Gravelines <> London for some minutes but will allow us to prevent the problem from occurring during the day.

explanation:
A bug on retransmission equipment causes a soft auto-reset (without impact) on the transponders after a given time (about 184j). This auto-reset workaround disables the software on optical CPAK making the links unstable.
