Re: DR plans?
I think quite the opposite.
Yes they've perhaps made some bad choices, and when they discovered and decided to move on from those bad choices, they didn't move quick enough to remove anything that still leans on the bad choices (the well documented power inadequacies, the "DC" made out of storage containers)
However if I have a service that is basically one set of stuff on one server, I always run the risk that if it breaks, gets nicked, goes on fire, or a plane crashes into the building, it's gone. 100% gone. Not that it might come back or is backed up somewhere by someone who's not me, or will get restored in good time. That it's gone.
That OVH is doing all this crazy reclaiming/cleaning/rehousing is - in most cases I understand - beyond what they're on the peg to do, and that's good for those that bought a service that might evaporate into thin air, crossed their fingers it wouldn't when they really ought not to have, and then their thing did indeed evaporate into thin air.
That there's people with services - critical or not - that they've not been able to yet rebuild elsewhere is striking. Not even a backup?! In fairness I have a service like this, and should it go pop it will be proper inconvenient, but I will cry to myself not to the provider.
That there's a high %age chance their data at least will be available once again to do something with seems to me to be very good service. I could easily see something like 1&1 or HostEurope going "ahh well there's that lot gone, sorry about that" and inviting you to start afresh with perhaps a few days of contractual service credit at best.
