We intervene this night (from 20 to 21/06) on London to migrate our two routers ldn-1 et ldn-5 to sup2T. The routers will be isolated (successively!) from the network the time of rhe maintenance. The raffic to UK and US/CA may be impacted during work. We start at 2:00 CEST.
Update(s):
Date: 2012-06-21 06:59:30 UTC We had some routing problems which has impacted the traffic between 04:00 and 06:00. BGP sessions to the route-reflectors are not mounted correctly on the new routers in sup2T, probably due to the incompatibility. We have updated one of the RF which has fixed the problem (https://status.ovh.net/?do=details&id=2946). New routers are in production.
Date: 2012-06-21 06:53:50 UTC Thereafter the wiring error on the site, the fiber dwdm to Roubaix has been cut and routing to ldn-5 (UK traffic) the US part of the interrupted backbone.
Date: 2012-06-21 02:08:15 UTC ldn-1-6k is cut. We are upgrading sup2T.
Date: 2012-06-21 01:16:14 UTC The router is up on sup2T. All links are reconnected. ldn-5-6k is performing properly. We are going to isolate ldn-1-6k.
Date: 2012-06-21 01:12:56 UTC We have switched off the router and we are replacing the cards of the chassis.
Date: 2012-06-21 01:09:56 UTC We are starting the work tasks on ldn-5-6k. We are isolating the router of the backbone.
