standard 99.900% 8.8 h/yrImportant: the SLA requires >=2 replicas for reads and >=3 for writes. A single-replica service has NO SLA — check your replica count.
standard 99.900% 8.8 h/yrProvisioned throughput deployments may carry different guarantees; multi-region routing is the usual resilience upgrade.

Deliberately not counted

known types, no own SLA
microsoft.web/sites Availability is determined by the App Service plan (microsoft.web/serverfarms), which we score. Counting both would double-count the same dependency.
microsoft.insights/webtests Monitoring configuration, not a runtime dependency of your application's availability.
microsoft.app/agents Preview service without a published SLA (as of last verification). We don't guess.
microsoft.app/managedenvironments SLA applies to the container apps inside it, not to the environment resource itself. Its zone redundancy setting affects the apps' resilience.
microsoft.insights/metricalerts Management-plane configuration, not a runtime dependency of your application's availability.
microsoft.network/networkwatchers Diagnostics tooling auto-created per region — not a runtime dependency of your application's availability.
microsoft.sql/servers The logical server is a free management container — the SLA applies to the databases inside it, which we score individually.
Draft values pending verification against current Microsoft SLA documents.
