Hosting SLA & Uptime Guarantees 2026: What You're Owed
What uptime SLAs typically promise, where the loopholes are, and how to claim a credit.
How We Evaluate Web Hosting
Our hosting reviews are editorial evaluations based on each provider's published plans, pricing, documentation, and policies, plus attributed third-party benchmarks where we cite them. We do not publish our own speed or uptime test results. Ratings are editorial opinions, not customer or lab scores. Some links are affiliate links; see our disclosure.
What an uptime SLA actually promises, and how to claim a credit if it is missed. Editorial note: HostPro Reviews has not run its own lab tests for this guide. Figures below are arithmetic, vendor-stated, or attributed to a named source.
What to look for in an SLA
- Scope: does it cover the server, the network, or your whole site?
- Measurement: who measures uptime, and how?
- Exclusions: scheduled maintenance, DDoS attacks, force majeure and customer-caused issues are commonly excluded.
- Remedy: credit amount and cap.
- Claim process: deadline and evidence required.
- Plan coverage: some hosts only offer an SLA on higher plans.
Green flags and red flags
Green flags: a written SLA, a public status page, a clear claim process and visible incident history.
Red flags: an uptime claim with no written terms, remedies that require you to prove downtime to the minute, or broad exclusions that swallow the guarantee.
How to claim an SLA credit
- Capture timestamped evidence, for example alert emails from a free uptime monitor.
- Check your host's SLA for the claim window.
- Open a ticket with dates, times and evidence.
- Ask the host to confirm the credit in writing.
Reliability vs price
Higher-priced managed plans often come with stronger commitments and redundancy, but a guarantee is only worth what the remedy and your evidence allow. For revenue-critical sites, consider your own monitoring and a backup plan rather than relying only on an SLA.
