source: live probes of Automattic hosts on 2026-07-31
notes: >-
  Automattic serves its RFC 9116 security.txt from the corporate host (automattic.com,
  mirrored on wordpress.com) and its OAuth/OIDC discovery documents from the API host
  (public-api.wordpress.com). The API host also still serves the legacy OpenAI plugin
  manifest for Jetpack, which points at a real OpenAPI document.
