CheckUpstream measured AWS KMS at 100.000% availability across 8492 independent checks (3 regions · kms). AWS publishes no catalogue of the services it reports on, so an incident reaches this page only when AWS names this product in the event itself. A quiet page here means AWS named no event for it — not that we have measured anything. No incidents have been recorded for AWS KMS in the past 12 months. Status signals are polled from AWS KMS's official status feed, alongside independent probes and community reports.

Sign up to CheckUpstream and add AWS KMS to a watchlist. We send incident alerts via Slack, email, webhook, or PagerDuty within seconds of detection, covering both the official status page and community signals (HN, Reddit, Bluesky, Cloudflare Radar).
We poll AWS KMS's official status page on a 1-5 minute cadence, parse its RSS / Atom feed as a fallback, ingest community signals from social platforms, and aggregate per-org SDK telemetry. Multiple sources reduce false positives versus any single feed alone.
