If you're a paying CircleCI customer, outages in these windows may count against CircleCI's SLA — vendors owe service credits for missed uptime targets, but only if you file inside the deadline. CheckUpstream tracks the entitlement, drafts the claim, and hands you the filing link.

CircleCI's 30-day customer-perceived uptime is 100.000%. 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.
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).
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.
