What is SLA uptime?

In short

SLA uptime is the share of time a provider commits to keeping your service reachable, and it backs most downtime promises.

SLA uptime is the share of the month a provider commits to keeping your service reachable, written as a percentage. It is the number behind most uptime promises and tells you how much interruption is allowed before you can expect credit. The figures here sit close together. 99.99% is the committed uptime at 1Gbits, 99.98% is the figure at 3v-Hosting, and 99.95% to 99.99% is the range AceCloud commits to. Compare that commitment against your own tolerance for downtime, not only against the next provider.
