We continue migration.

This week is Amsterdam! :)

The first step of this migration will replace ams-1-6k in a configuration "on a stick" by cutting a nexus7706 (2 * 48 + 2 * 10G * 12 * 100G) and a ASR9904 (2 * 2 * 8 + RSP880 * 100G).
Once this is done, we will be able to connect different 100G ports on the backbone and it will be time to upgrade AMSIX in 100G.

The migration begins tomorrow at 00:00.

We're nearly ready. We will isolate the router in a few minutes.


Comment by OVH - Thursday, 04 June 2015, 10:57AM

Router is isolated. We will cut it off from the electric supply! Let's rock n roll!


Comment by OVH - Thursday, 04 June 2015, 10:58AM

The N7 and ASR are up. We will remount the physical links then gradually put the traffic back into production.


Comment by OVH - Thursday, 04 June 2015, 10:59AM


All our outbound links are back in production.

We will carry out some checks then we will complete the Amsterdam migration tomorrow night: we will install ams-5-n7 and ams-5-a9!

We're getting ready to replace ams-5-6k which will not necessarily be taken totally out of action, but will become ams-20-6k to maintain the CDN routing.

We will isolate the router in 30 to 40 minutes.

Beginning the migration. First step: isolating the router.


Comment by OVH - Thursday, 04 June 2015, 11:02AM

Cutting off power to ams-5-6k!


Comment by OVH - Thursday, 04 June 2015, 11:02AM

We're gradually remounting the traffic.


Comment by OVH - Thursday, 04 June 2015, 11:03AM

All is up :)


Comment by OVH - Thursday, 04 June 2015, 11:03AM

We're isolating AMS-IX on ams-1-a9 to upgrade to 1x100G.


Comment by OVH - Thursday, 04 June 2015, 11:05AM

We've remounted ams-1-a9 and put into production the 100G link.

This bug is vicious and caused us to lose a lot of time :(

All is fine now!

We will contact the manufacturer to investigate and get a patch.
