Mux's last resolved incident started 6 days ago and lasted 28 minutes (degraded performance).
Mux'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.

Its primary product surface is an API, along with web-based tools for monitoring service status and managing video workflows.
We poll Mux'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.
