Key Evidence

• Duplicate of #10459: Issue #10459 ("Issue uploading large number of small, static assets") describes the exact same problem with similar file counts (~10,000 files). It has:

  • Active maintainer engagement (@emily-shen, @matthewdavidrodgers, @penalosa)
  • Internal Jira tracking: WC-4097
  • internal label indicating Cloudflare Platform team involvement
  • Recent activity (January 2026)
  • Multiple affected users providing account IDs for debugging

• Root cause: Server-side throttling/timeout when uploading large numbers of assets. The Cloudflare API cannot handle sustained high-volume asset uploads without timeouts.

• API-side changes made: @emily-shen commented on 2025-09-12 that API changes were deployed to help, but issues persist per later comments.

• Secondary feature request: User also requests a progress bar for the file analysis phase. This is unaddressed but lower priority than the core upload failure.

Recommendation

Status: CLOSE

Reasoning: This issue is a duplicate of #10459, which has significantly more context, maintainer engagement, internal tracking (WC-4097), and multiple users contributing debugging information. Consolidating discussion in #10459 will help the team resolve this faster.

Action: Close as duplicate of #10459.

Suggested Comment

Thank you for reporting this issue and providing detailed logs!

This appears to be a duplicate of #10459, which tracks the same problem of Pages deployments failing when uploading a large number of static assets. That issue has ongoing investigation with the Cloudflare Platform team (tracked internally as WC-4097).

I'm closing this as a duplicate to consolidate discussion. Please subscribe to #10459 for updates on the fix. If you can provide your account ID and project name in that issue, it would help the team investigate further.

Regarding your feature request for a progress bar during the file analysis phase - that's a good suggestion! If you'd like that tracked separately, please open a new feature request issue for it.
