Can confirm its OVH, its actually one of the largest provider in the world and they have fucked up something seriously .
I have few stuff with OVH, everything is in dark atm.
If its power failure, then its not serious bussiness...I mean, how can you
be serious datacenter without backup servers located very far from each other
I think its probably software attack or bug, but they don't want to ruin
reputation by admitting it
So far, it appears they had some routing issue, they are not only one of the largest but also have some very innovative stuff in their arsenal to handle millions of server hosted with them. And I guess their routing thing had some single point of failure which fucked up their most of datacenters.
Now they are back, almost all services are restored, now awaiting them to disclose real reason apart of generator ditching in time of need.
