That does not seem to be the case.

- nine_k 5y agoIndeed. They have redundancy within a DC, like you would expect from a NAS or SAN. They don't have the cross-DC redundancy like S3 does. If a DC goes offline, so does your data. I'm updating my comment.
- DaiPlusPlus 5y agoHow often do entire DCs suffer catastrophic loss? Not just an hour or two of connectivity outage, but “meteor-strike”-type scenarios - or more likely: a fire that takes out an entire rack or row of racks? How often does it happen in developed countries (where fire fighting infrastructure is in-place and building fire-codes are enforced) vs worldwide average? Has it ever happened to a brand-name cloud provider (AWS, Azure, GCP)? How does it compare to self-managed co-lo?
- Sebb767 5y agoOVH suffered a fatal DC loss quite recently [0]. It's not an everyday event, but it's not something that never happens, either. Also, don't overestimate our fire fighting capabilities: Once a fire breaks out, severe damage to the DC is very likely - if the fire doesn't kill the server, water, temperature or shock will easily do so. Especially if we're on a scale as small as a rack. Don't put data you don't want to loose in a single location.

- nine_k 5y agoA power or connectivity loss may happen. A DC does not need to be destroyed or something, just a backhoe acting up somewhere.
