## Package/OS mirror networks: listed but not synced

- Arch Linux mirror status JSON: active true doesn't mean synced, 207 active mirrors show 0pct completion. [obj_01M45YMWWW53NY9KK5BZSVVP0S]
- Debian's official mirror list has zero Packages-over-HTTPS entries, only HTTP and rsync. [obj_01M45YMQR8KMFPXEYEDQWYH2P9]
- Fedora MirrorManager: an invalid repo/arch 404 embeds every valid repo/arch combination it recognizes. [obj_01M45YMTB0J7X1JB55WV768PVW]
- opam has no REST API either: a 5.1 MB index.tar.gz mirror and a 1.5 KB repo config file with client-version-gated announcements. [obj_01M45FKD4DCCARGB61G30BHXAB]

## Mirrors as the real access path

- Radio Browser API — DNS SRV mirror discovery, UA requested but not enforced. [obj_01M45GK0YSHXDRTDPT1DD4H9WB]
- GeoNames. [obj_01M4V8RHEMD3DN23DY04558SZS]
- Bazel Central Registry: bcr.bazel.build serves valid module metadata as real JSON, but a missing module 404s into an HTML page whose only content is a client-side JS redirect. [obj_01M45WY04R63SKZKFAZZCJ53Q3]
- OurAirports' open CSV mirror (davidmegginson.github.io/ourairports-data) is a labeled, header-row dataset. [obj_01M45D3QTRNZRQJX8HGBB7N2P0]

## Cross-protocol mirrors with subtly different shapes

- Europe PMC mirrors PubMed's retraction text (`pubType`) with no separate structured flag of its own. [obj_01M4RZ1RMNHQHNDRAXKZMK7C40]
- Handle.net proxy (hdl.handle.net) mirrors doi.org's api/handles JSON shape for known handles. [obj_01M45MMK3V570KGFGG0MT6W0F0]
- .NET releases-index.json: support-phase states plus null eol-date for not-yet-reached channels, mirrored on two CDNs. [obj_01M45MK6JNFPDJBKH1ZMKEPP7M]

## Disagreements and open questions

- US-Germany mirror trade statistics, 2022: US-reported exports ($72.5B) vs Germany-reported imports from the US ($100.3B) - a 38% gap. [obj_01M4RZ2WVT10R8T2H3VJQA4M12]
- PyPI's two keyless, no-BigQuery download-stats mirrors agree on nothing but the header name. [obj_01M4V8KN8QG2MA17B6ZKST929D]

## Possibly stale

- prefix.dev's "fast" conda-forge repodata_shards mirror is over a year stale; the canonical conda.anaconda.org copy updates within hours. [obj_01M45XYJTVSWZXMBMAD29ZHFYJ]
- The AWS-hosted Mapzen/Terrain Tiles mirror is a frozen 2017 snapshot served straight off S3. [obj_01M45KVE35AAXEZDPJRYN60YYM]
- Staleness hides behind HTTP 200 across cloud-native infra mirrors — three decreasing degrees of silent drift, ranked. [obj_01M45XYYHYH2QWXWNGDT68P6T9]
