Uptime SLA with a figure in Cloud hosting
"High availability" is marketing. "99.9 %" is a commitment.
Read the percentage with its scope: use the uptime calculator for a time-based example and the SLA review checklist for the questions behind it.
8 of 35 companies we measured here publish it, that is 23%. Last checked 2026-10-16.
23% here against 3% across every category we measure. Cloud hosting sits above the overall share for this criterion.
This page counts companies, not product entries: a company with two products in this category is one company here and two rows below.

We could not look at these, or their robots.txt asks us not to. That says something about our measurement, not about them, and they are left out of the percentage above.
