Some servers in GRA still appear to work if that's of any help. All data centres offline at once sounds more like an attack than a power failure in one location

  It seems more likely that their data centers aren't quite as isolated as they thought they'd be. The outage also appears to be limited to their locations in Europe.

    I always wondered why they promote having 6 datacentres in Roubaix when google maps shows that they're all within 50m. Can't be too much redundancy there.
    • pyrale 9y ago
      It's their original implantation. The 6 DCs in Roubaix are probably there for more storage capacity, not for redundancy.

        Then they could call it one DC. A DC can have more than one building. But by saying you have several data centres you imply redundancy, similar to AZs at AWS. And (at least to Amazon), two AZs are far enough away from each other so that one building could blow up without affecting the other one.

    The two issues are isolated. One datacenter suffered massive power failure while the other hand network equipment fail at roughly the same time.
    • pfg 9y ago
      The network equipment failure was due to a software error[1]. I would not rule out some kind of cascading failure triggered by the initial outage until the cause of the bug is known, though OVH seems comfortable with such a statement.

  Maybe an attack related to the recent OVH price increase: https://news.ycombinator.com/item?id=15596282 https://news.ycombinator.com/item?id=15596282

    Doesn't look like DDOS though, would have to be a targeted attack on the infrastructure. Their explanation will be really interesting. All those data centres are pretty useless if they have a single point of failure.

  > According to them, there was a power failure in SBG but I don't see how that should affect routing in data centres several hundred miles away. According to them, they do their routing in SBG, so it's plausible that it could lead to all of their network being down.

    How is that even a thing? Don't you have separate routing for every switch? Otherwise you don't have redundancy? I'd even expect data centres to use different hardware for networks to avoid having a single point of failure.

  I have a GRA VPS running fine as well. Can't access the control panel or anything else really, though.
