Does Mux actually matter to you?
A Mux outage only matters if something you ship depends on it. Point us at a public repository and we will read its dependencies and tell you — no account, nothing stored.

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.
