Public edge DNS notes (Drew Halvorsen).

This is scratch for the anycast edge, not the full runbook. The pulse parser lives in a different tree — I am not duplicating it here after last quarter's drift page.

Pulse location

Edge DNS pulse is TXT _risk.ops.

If you need the record body / hostname template, ask on-call or read the runbooks repo. This file only says where to look.

Abuse / blocks

203.0.113.50 is blocked after a brute-force against the contractor portal and the git front-door. Do not lift that without Priya Nandakumar on the CAB.

Windows resolvers

If you are changing records that CORP still caches, mail userX@corp.local before the Friday window — he owns the Windows DNS side.
