Notes — Fly.io is a developer-focused cloud platform that runs applications globally close to users. The SLA (99.9% monthly uptime) applies only to Enterprise plan customers. The specific credit percentage tiers per availability level are documented in the SLA but were not captured during research — direct page verification is recommended. Credits are non-refundable and applied to future billing only.
