v27 nightly releases missing from https://nodejs.org/download/nightly/ directory

[MikeMcC399]

I can't find any releases with v27.0.0* in the directory https://nodejs.org/download/nightly/

The last previously listed nightly is:
https://nodejs.org/download/nightly/v26.0.0-nightly20260417b178842482/ from Apr 2026

https://nodejs.org/download/nightly/index.json on the other hand shows:

[
  {
    "version": "v27.0.0-nightly202609067aba44d4ac",
    "date": "2026-09-06",

but

curl -I https://nodejs.org/download/nightly/v27.0.0-nightly202609067aba44d4ac/

produces only HTTP/2 404.

They are on the origin server: https://direct.nodejs.org/download/nightly/

@targos

They are on the origin server: https://direct.nodejs.org/download/nightly/

Are you able to pinpoint why they're not getting promoted to https://nodejs.org/download/nightly/ or does this need help from @nodejs/web-infra ?

Only closest issue I see is #1006

I forwarded this to the team, btw

AFAICT the nightlies are in both the staging and production R2 buckets, e.g.

[araujogui]

Had a look at this. Only the directory listings are broken; the files themselves are in R2 and download fine:

$ curl -sI https://nodejs.org/download/nightly/v27.0.0-nightly202609067aba44d4ac/ | head -1
HTTP/2 404
$ curl -sI https://nodejs.org/download/nightly/v27.0.0-nightly202609067aba44d4ac/node-v27.0.0-nightly202609067aba44d4ac-linux-x64.tar.gz | head -1
HTTP/2 200

So it's a worker bug, not anything on the build or upload side.

Since #1002, prod has served the nightly/, rc/, v8-canary/, test/ and docs/ listings out of a KV cache, and nothing refreshes it. The rebuild is manual only, and it last ran on 2026-04-17 and failed. That's also where the working nightlies stop. On a cache miss the worker just 404s instead of falling back to listing the bucket.

Re-running Build Directory Cache workflow should fix the issue. Longer term it probably needs a scheduled refresh, and a cache miss should fall back to the bucket rather than 404ing.

I'm going to move this to https://github.com/nodejs/release-cloudflare-worker as it sounds like the issue is there.
