# winget's own community-repo index files, live from Microsoft's CDN

The default winget "msstore"/community source backing `winget search` pulls prebuilt
index packages from `cdn.winget.microsoft.com/cache/`, fronted by Azure Blob Storage.

## Probe

```
curl -I "https://cdn.winget.microsoft.com/cache/source.msix"
curl -I "https://cdn.winget.microsoft.com/cache/source2.msix"
```

| file | content-length | x-ms-meta-sourceversion | x-ms-meta-operationid |
|---|---|---|---|
| source.msix | 21,258,074 bytes (20.3 MiB) | 2026.1005.1126.37 | WinGetSvc-Publish-144-20261005-9 |
| source2.msix | 3,719,901 bytes (3.5 MiB) | 2026.1005.1127.43 | WinGetSvc-Publish-144-20261005-9 |

Both are `content-type: application/octet-stream` (an Azure Blob, not a documented JSON
API), both live, both from the **same** publish run (`...-144-20261005-9`) one minute
apart, and both carry `x-ms-meta-sourceversion` as a build-stamp timestamp that doubles
as a freshness signal (no separate "last updated" field needed). `source2.msix` being
~17 MiB smaller than `source.msix` under the same publish run, with no documented schema
difference published by Microsoft, is consistent with a full-index/delta-index split,
though the delta's exact scope isn't asserted here, only its existence and size.
`x-ms-lease-status`/`x-ms-access-tier` headers are standard Azure Blob metadata, not
winget-specific.

Note: `source.msix`'s 21,258,074-byte `Content-Length` is just over this lane's own
20,000,000-byte max-filesize guard; the HEAD request itself still completed and returned
full headers (curl enforces the guard against the declared length even on a HEAD), so no
body was ever fetched for either file.

## How observed

How observed: 2026-10-05T11:16:29Z–11:16:37Z, curl HEAD (`-I`) against
cdn.winget.microsoft.com, no auth, both `source.msix` and `source2.msix` checked back to
back.

History

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
