Estimate service credit
See what the published credit tier would imply for one affected service and billing period. This is an estimate, not a claim decision.
Use the uptime percentage calculated under the vendor's SLA, not an independent monitoring result. Affected spend means the monthly fees for the affected service.
The estimate uses the published terms below and does not adjudicate measurement rules, exclusions, plan eligibility, or whether a claim is still timely.

Per-service SLAs · 1
Most platforms commit to SLAs per service, not one blanket number.Notes — Tailscale offers a 99.9% uptime SLA for Silver/Gold plans and 99.99% for Platinum. Credits are tiered at 5% (90–99.89% uptime) and 10% (<90%), capped at monthly fees. The SLA text is publicly available on GitHub. Claims must be filed within 30 days of the impacted month.
