Summary

Removes https://v.monophonic.digital from ProdUploadNodes, leaving creatornode.audius.co as the only upload target the API advertises in /health_check.

Why

Album uploads have been stalling at a few percent and then failing for users whose SDK rendezvous picked monophonic. Over the last 24h, 100 of the 112 audio uploads stuck in new with no CID were created on monophonic, and the same WAV files that failed there repeatedly succeeded first try on creatornode.

Probing both nodes with real tus uploads shows the difference is the Cloudflare zone in front of monophonic, not the node software (both run the same build):

  • HEAD /files/:id arrives at tusd as GET and returns 405, so tus-js-client can never read its offset to resume after an interruption. Progress freezes where the first attempt stopped, then the upload fails once retries are exhausted.
  • A PATCH whose body takes longer than ~100s is cut off with a 524. Album tracks upload concurrently, so a 150–200MB album on a home connection routinely exceeds that per request.
  • /uploads/:id is served from cache (cf-cache-status: HIT on the second poll).

creatornode passes all three checks.

The node remains in StoreAllNodes and the artist coin reward sender list, which do not depend on the upload path. It can be re-added once the zone bypasses cache on /files/* and /uploads/* and stops rewriting HEAD.

Test plan

  • go build ./... and go vet ./config/ pass.
  • After deploy, curl https://api.audius.co/health_check | jq .data.network.content_nodes should list only creatornode.

🤖 Generated with Claude Code

Resumable (tus) uploads cannot complete through the Cloudflare zone in
front of v.monophonic.digital: HEAD /files/:id reaches tusd as GET and
returns 405, so a client can never learn its offset to resume after an
interrupted PATCH, and PATCH requests lasting longer than ~100s are cut
off with a 524. /uploads/:id responses are also served from cache.
Roughly half of album uploads have been landing there by rendezvous and
stalling at a few percent before failing.

Route prod uploads to creatornode.audius.co only until the zone is fixed.
The node stays in StoreAllNodes and the reward sender list, which do not
depend on the upload path.
