MajorFrequently Asked Questions
Is CircleCI currently down?
CircleCI is currently Operational. CheckUpstream tracks CircleCI in real-time across the official status page, RSS / Atom feeds, and community telemetry — refresh this page for the latest reading.
When did CircleCI last have an outage?
CircleCI's last resolved incident started 2 days ago and lasted 1h 14m (degraded performance).
What's CircleCI's 30-day uptime?
CircleCI's 30-day customer-perceived uptime is 99.566%. The figure is weighted (full-outage = 1.0, degraded = 0.3) so component blips don't collapse the score the way a raw incident-count would.
How do I monitor CircleCI in production?
Sign up to CheckUpstream and add CircleCI 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).
How does CheckUpstream track CircleCI?
We poll CircleCI'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.
