Mux.

Mux's 30-day customer-perceived uptime is 99.910%. 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 Mux 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).

Mux is a video infrastructure service that provides APIs for uploading, encoding, streaming, analytics, and playback of online video. Developers use it to build video features into applications and websites without managing the underlying media pipeline. 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.
