# Datasette's standalone demo hosts are being folded into datasette.io

`global-power-plants.datasettes.com` was a standalone Datasette demo
(Simon Willison's per-project `*.datasettes.com` pattern). It is no longer
one.

## Probe 1 — the old host redirects away from itself

`GET https://global-power-plants.datasettes.com/.json` -> `HTTP 301`,
`Location: https://datasette.io/global-power-plants`. The dedicated
`datasettes.com` subdomain now exists only to redirect into a single
consolidated `datasette.io` instance that hosts many former demo databases.

## Probe 2 — the merged instance carries the real dataset

`GET https://datasette.io/global-power-plants.json` -> `HTTP 200`:
```
{"database": "global-power-plants", "path": "/global-power-plants",
 "tables": [{"name": "global-power-plants", "count": 33643}, ...]}
```
33,643 rows — a real, much larger table than the `fixtures` demo's biggest
(1,001 rows), useful for confirming the row ceiling isn't fixtures-specific.

## Probe 3 — identical ceiling behavior on the merged host

`GET https://datasette.io/global-power-plants/global-power-plants.json?_shape=array`
(no `_size`) -> `HTTP 200`, exactly **100** rows (same default as
latest.datasette.io).

`GET .../global-power-plants.json?_shape=objects&_size=max` -> `HTTP 200`,
`rows` has exactly **1,000** entries, `"truncated": false`, `"next": 1000`.

`GET .../global-power-plants.json?_size=1001` -> `HTTP 400`:
```
{"ok": false, "error": "_size must be <= 1000", "errors": ["_size must be <= 1000"], "status": 400}
```
Byte-identical error body to the `fixtures` instance (see the sibling
`latest.datasette.io` source) — the 100-row default and 1000-row ceiling are
Datasette-the-software defaults, not per-deployment configuration, confirmed
across two independently-hosted instances and two very differently sized
tables (1,001 vs 33,643 rows).

How observed: 2026-10-05T12:36:09Z-12:36:26Z, plain `curl` GET, no auth,
following the one redirect manually to confirm its target before probing the
merged host.

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.
