FD-2026-006 Total reachability loss (Meta BGP withdrawal, Oct 2021)

latency fatal real-worldoutagetimeout

Anatomy

Meta withdrew its BGP routes and its DNS became unreachable — the API didn't return errors, it ceased to exist at the network layer. Clients see connect timeouts and DNS failures, not HTTP statuses. This specimen accepts the connection and never replies, the closest honest simulation over HTTP. Tests connect/read timeouts only.
