Authentication requiredReachable; initialization requires authentication.
Since Aug 11, 2026 — 9:25 AM (83 d ago)

An authentication challenge is availability, not an outage — the endpoint is reachable and answering. Passive observation records the challenge and any OAuth discovery metadata without ever authenticating. OAuth-authenticated contract monitoring is planned.

Baseline captured — authentication required Informational Aug 6, 2026 — 5:30 AM
Endpoint is reachable; initialization requires authentication. Passive observation records availability, latency, and protocol behavior only.
Verifiedinitialize returned HTTP 401.
InterpretationAuthenticated contract monitoring can be added later (OAuth support planned).
