I would assume that if one of their datacenters became partitioned from the others in the group, then they would stop serving requests out of that DC entirely.

I would assume that if one of their datacenters became partitioned from the others in the group, then they would stop serving requests out of that DC entirely. This would alleviate the concern for network partition-tolerance, wouldn't it?
- rbranson 16y agoThe problem is that C systems have masters. What happens when the master becomes network isolated? The election and recovery process is tricky. If 100% consistency is assumed, there MUST an outage period until this is recognized and corrected.
