Dependency truth pages
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.
Where the vendor may be under-reporting
Independent probes could not reach these service hosts while the vendor status page claims operational. We do not dispute a vendor outage report from a reachability handshake alone.
- E2E Test Provider: We measured UNREACHABLE; E2E Test Provider reports operational

We independently ping each service host (reachability only) and also read its status page. The strong public signal is unreachability while the vendor claims operational.
Providers we cannot probe independently are labeled not independently probed yet and are never shown as healthy. Gaps in coverage are honest limits of this measurement surface, not implied uptime.
