# Ubuntu cloud-images simplestreams: a dead cloud left in the index

`cloud-images.ubuntu.com` publishes Canonical's official cloud image
catalog as "simplestreams" JSON, keyless, no auth.

## Probe 1 — top-level index

```
curl -s https://cloud-images.ubuntu.com/releases/streams/v1/index.json
```

## Observed

HTTP 200, `content-type: application/json`, 30,013 bytes, `format:
"index:1.0"`. The `index` object lists 8 product streams. Seven have
non-empty `products` arrays with `updated` timestamps in 2023–2026. The
eighth, `com.ubuntu.cloud:released:rax` (Rackspace), has **`"products":
[]`** and **`"updated": "Wed, 29 Apr 2020 21:11:13 +0000"`** — over 5
years stale at probe time, yet it is still a live top-level entry in the
index with a valid `path` (`streams/v1/com.ubuntu.cloud:released:rax.json`)
that any index-walking client would attempt to fetch. Rackspace's own
Ubuntu cloud offering shut down years ago; Canonical never removed the
pointer, it just stopped populating `products`.

## Probe 2 — the `download` stream (the real catalog)

```
curl -s https://cloud-images.ubuntu.com/releases/streams/v1/com.ubuntu.cloud:released:download.json
```

## Observed

HTTP 200, `content-type: application/json`, 18,608,100 bytes (18.6 MB,
single file, no pagination). `datatype: "image-downloads"`, 166 product
entries spanning every release back to `com.ubuntu.cloud:server:10.04:amd64`
(Lucid, EOL since 2015) — stale releases are kept in this stream
permanently, unlike the `rax` entry above which was emptied in place.
Each `versions.<date>.items.<ftype>` leaf carries `size` (integer bytes),
`md5`, and `sha256` directly alongside the relative `path`, e.g. for
Lucid's `disk1.img`: `"size": 226099712, "sha256":
"983b7be9dd1ed8c0b3118e309cdd2b2869b74ddcbb3e4c6c4c77e28e0a7b5e59"`.

## How observed

2026-10-05T11:45:43Z–11:45:50Z UTC, `curl` GET (default UA), both files
fetched directly with no auth; `--max-filesize 20000000` left ~1.4 MB of
headroom on the 18.6 MB download stream.
