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.

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.

Someone with access might wish to update the title of this post, because all OVH datacenters are definitely not down.

exactly, german datacenter is operational without any problems yet

I'm trying to find ETA for solving the issue, but they didn't post it on Twitter. Anybody knows ETA?

They haven't posted any ETA yet.

I moved away from OVH after I paid 3 months advance (~$300) for a server which burned down after 1 1/2 months. They did not issue any refunds (data, blood, sweat and tears were lost that day). I have been an OVH customer for 12 years. Today, I'm glad to have moved away all my production environments as well.

Just an good advice: Never ever trust a single point/server without backups. Do backups, do snapshots (check if and how you can do that), store them somewhere else. Try to do automated reinstall with e.g. Ansible so that you can move easily. It's an investment at the beginning and during running the server but if the stuff is critical you should always do that.

My server hosted on OVH had some problems (DNS lookups) but has stayed up and works fine right now.

EDIT: Hosted in EU.

That seems a little uncharitable.

If the SBG issue really triggered the outage for the whole network I find it hard to believe that no one saw that problem beforehand. They probably thought that this was too unlikely to happen or that there are other failovers but never tested them properly. No expert on the field but that's the first time I can remember that a provider of that size loses connection to most of their data centres at once. That can hap…

What is SBG? A CDN of some sort?

It's the location of one of their data centers. SBG for Strasbourg.

In this case, I wouldn't be to hard on them. As it appears they lost their main power line, the backup power line and both generators failed and one generator has been restarted now.

It's a collection of datacenters in Strasbourg.
