- zzzcpan 8y agoThat's rather vague definition. And is also wrong. They obviously can't guarantee global consistency within 10 sec, as that would require consensus which is impossible to guarantee in bounded time and they probably don't even use any consensus algorithm at all, as that would be pointless for a CDN.
- kentonv 8y agoYes, in the presences of a network partition, propagation can take arbitrarily long. But, that would be classified as an outage. Knowing the typical non-outage delay is useful.
