Diagnosed azcomputerguru.com 521 errors: Cox's BGP route to specific Cloudflare origin-pull prefixes (162.158.0.0/16, 172.64.0.0/13, 173.245.48.0/20, 141.101.64.0/18) is broken from 72.194.62.0/29. Confirmed by TCP probe matrix from pfSense WAN, traceroute latency comparison, and state-table showing 0 inbound CF connections while direct-internet traffic still reached origin. Deployed Cloudflare Tunnel 'acg-origin' on Jupiter Unraid as a Docker container. Routes 4 proxied hostnames (azcomputerguru.com, analytics., community., radio.) through the tunnel with HTTPS backend to IX 172.16.3.10:443 with per-ingress SNI matching. All 4 hostnames return 200 OK through CF edge after the cutover. Repo hygiene: - Merged clients/ix-server/ into clients/internal-infrastructure/ (IX is internal infra, not a paying-client account). Git detected the session-log files as renames so history is preserved. Updated 4 stale path references in 2 files. - Moved cox-bgp ticket draft out of projects/dataforth-dos/ (wrong project) to clients/internal-infrastructure/vendor-tickets/. - Relocated tunnel-setup helper scripts from projects/dataforth-dos/datasheet-pipeline/implementation/ to clients/internal-infrastructure/scripts/cloudflared-tunnel-setup/. Deleted superseded/abandoned login attempts. Sanitized hardcoded Jupiter/pfSense SSH passwords to pull from SOPS vault at runtime; Cloudflare token reads from env var (tokens still in 1Password, vault entry is metadata-only).
