Is Mux down right now?
Our independent multi-region reading is: reachable.
Independently measured by StackWitness. We ping each service host ourselves (reachability) and also read its status page. The strong signal is when a host is unreachable while the vendor claims operational.
Current status
Independent reachability and the vendor status page currently point the same direction.
reachable = the service host answered our probe; not a guarantee the product is fully healthy

Probe latency (this week)
Probe round-trip time and reachability outcomes only. Not full product health or a vendor SLA.
Stable · ~324ms p50 · scale fits this week’s range (not a fixed 0-100ms axis)
Line / fill = successful probe p50 · Bands = disruption windows · Floor ticks = fail share in bucket
No significant probe-latency or reachability disruptions in this window.
How to read this page
StackWitness shows two columns for Mux: independent multi-region reachability (our probes of the service host) and the vendor's own status page (self-report). Divergence matters most when we cannot reach a host the vendor still calls operational. Reachable means the host answered our probe; it is not a promise every feature works, and we never issue a compliance verdict.
Questions
Is Mux down?
StackWitness independently pings the Mux service host for reachability from multiple regions and also reads the vendor status page. Reachable means the host answered our probe; it is not a claim that every product feature is healthy. We never issue a compliance verdict.
How does StackWitness know if Mux is down?
We ping the Mux service host for reachability from multiple regions and read the vendor status page. The signal worth acting on is when we cannot reach a host the vendor still calls operational.
What does "reachable" mean here?
The host answered our probe from our regions. It is not a claim every Mux feature is healthy, and we never issue a compliance verdict.
