Just a short notice. Our provider is not really happy with the stability of the routing. Basically, they try to get better BGP performance (I have no idea what it really means) and this requires some hardware changes and some experimentations. They are pretty good at doing that within minimum impact, but still, you may notice some downtime here and there. The downtime may not be full as this can come from partial announce of the routes.
Also, they are working on the UPS system because of minor warnings, the UPSes are complaining about fan problems even so the fans are running normally. The maintenance team of the UPS provider is on site to take care of the problem.
I really appreciate how open OVH is when dealing with their internal issues (their bug tracker is simply open to everyone), this is why Indefero is hosted with them.
Update: Everything is under control, no rotuing issues anymore and the UPS are under stricter control for a while.
