cloudflare JAX colo failing R2 custom-domain fetches for plyr.fm media #

date: 2026-08-27 status: unacknowledged by cloudflare status page impact: users routed to the JAX (Jacksonville, FL) colo cannot load audio or cover art — player shows NaN:NaN duration, images fail. all other colos healthy.

symptom #

user report: track page/embed loads (title, artist), but audio never loads (NaN:NaN) and cover art is missing. reproduced across firefox, chrome, and safari on the same machine — i.e. below the browser.

user devtools showed the smoking gun:

GET https://images.plyr.fm/images/<id>.jpg → HTTP 500
server: cloudflare, cf-cache-status: BYPASS, content-type: text/html, 0 B body
cf-ray: a31cbef0bed07221-JAX

not a bot challenge (would be a 403/challenge page; same-zone page assets load fine).

evidence #

zone analytics (GraphQL httpRequestsAdaptiveGroups, zone plyr.fm / 2bfcb9ffe7847604e9febbb62d9649a3):

last 6h, edgeResponseStatus >= 500 on audio.plyr.fm + images.plyr.fm:
- images.plyr.fm: 17× 500, 14× 502 — all coloCode JAX
- audio.plyr.fm: 7× 500 — all coloCode JAX
- zero 5xx from any other colo
23h time series at JAX for those hosts: 63 requests, 100% 5xx, 0 successes, first bucket 17:00Z (no JAX media traffic before that, so onset is "at or before" 17:00Z)

healthy-path verification from another colo (same URLs):

Range: bytes=0-1 on the wav → 206, access-control-allow-origin: *, correct content-range
cover art + thumbnail → 200, cf-cache-status: HIT

ruled out:

origin/R2: other colos serve the same objects fine
our config: no zone changes; errors are colo-scoped
user machine/DNS: DNS resolves normal dual-stack cloudflare IPs; no DNSSEC on zone; failure followed the colo, not the client
cloudflare status page: no incident, no JAX maintenance scheduled or in progress, JAX component "operational"

affected surface #

audio.plyr.fm and images.plyr.fm — R2 custom domains behind the plyr.fm zone. api.plyr.fm (fly.io, separate path) unaffected, which is why pages render but media fails.

ray ID: a31cbef0bed07221-JAX
zone: plyr.fm
hosts: audio.plyr.fm, images.plyr.fm (R2 custom domains)
behavior: 500/502 with cf-cache-status: BYPASS on edge→R2 fetch, JAX only, since ~17:00 UTC 2026-08-27; 100% failure rate at that colo, zero 5xx elsewhere
