Datacenter fires cause downtime no matter what consistency model you choose.
Also, mainframes are pretty big, multi-processor machines. They have their problems, but having all those components give out all at once? I'm sure it happens, but I've never heard of it.

- djha-skin 3y agoIn theory yes, and certainly if we're talking about Cassandra. In practice, most people do not distribute over multiple data centers. Doing so is very difficult and costly.
- valenterry 3y agoHaha, I've been there. Three companies I've been with have done that - and every time we had more downtime overall than had we just run a mirrored postgres. But yeah, the theory is what I'm talking about. Not putting the theory into practice is a whole different matter. :-)
