Description
Old Hetzner Falkenstein hub IP `89.167.57.232` still appears in hydraguard docs after the migration to OVHcloud Brussels (`hydraguard.experiencenet.com` → `141.227.136.199`).
Known occurrences:
- `hydraguard/CLAUDE.md` line 9 (Hub server) — needs full replace
- `hydraguard/docs/runbooks/air-body.md:22` and other steps reference `ssh root@89.167.57.232`
- Possibly other repo-internal references — sweep with `grep -rn 89.167.57.232 .`
The new hub is `141.227.136.199`. Prefer the DNS hostname `hydraguard.experiencenet.com` over the literal IP wherever practical (matches the redaction posture for the public-facing hydraneck docs we shipped today — see #142 prep work).
## Verification
`grep -rn 89.167.57.232 .` returns no matches in the hydraguard repo.
