Customer.io's last resolved incident started 3 days ago and lasted 34 minutes (degraded performance).
Customer.io'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 Customer.io 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 Customer.io'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.
