We are going to upgrade these equipment in order to improve the stability and also to add new functionalities. No impact on the traffic as we will isolate both routers before the maintenance.

We plan to do this task next Wednesday 23th of August 2017 at 8:00am (UTC).

We start the isolation


Comment by OVH - Wednesday, 23 August 2017, 10:14AM

Traffic is isolated, we reload the first router.


Comment by OVH - Wednesday, 23 August 2017, 10:40AM

We reload the second router.

We have an unexcected behaviour bhs-g1-nc5, we investigate


Comment by OVH - Wednesday, 23 August 2017, 11:22AM

All the routing sessions are okay on the equipment but we cannot connect directly on it. We are still investigating.


Comment by OVH - Wednesday, 23 August 2017, 12:00PM

We are opening a priority 1 ticket with the manufacturer.


Comment by OVH - Wednesday, 23 August 2017, 13:27PM

The impact seems to only be on the control plane, no impact on the flow going inside the NCS5. We are still debugging with our manufacturer. As some links become loaded, we will put back the router in production soon.

We reduce the amount of trafic on bhs <> chi to have more time to debug


Comment by OVH - Wednesday, 23 August 2017, 14:16PM

We found the issue source, we will be able to put back the equipment in production in the next minutes.


Comment by OVH - Wednesday, 23 August 2017, 14:28PM

The router is back in production.
