# British Library: SRU and linked-data hosts no longer answer

Three documented British Library data-access hosts were probed; none serves data any more.

## Probe 1: SRU

```
GET http://sru.bl.uk/SRU?version=1.1&operation=searchRetrieve&query=cql.anywhere=education&maximumRecords=1
```
`curl: (6) Could not resolve host: sru.bl.uk` — DNS failure, not a server-level refusal.

## Probe 2: the BNB linked-data host

```
GET https://bnb.data.bl.uk/
```
DNS resolves (`194.66.233.215`), but the connection itself fails: `curl: (7) Failed to connect … Network is unreachable` — a routing-level failure distinct from both DNS failure and a TCP refusal.

## Probe 3: data.bl.uk, the umbrella data-platform host

```
GET https://data.bl.uk/
```
`302` → `Location: https://www.bl.uk/` — the British Library's data/linked-data platform host now redirects straight into the main marketing site rather than serving a catalogue or API landing page.

Together these three results (DNS-dead, unroutable, redirected-away) describe the same underlying fact three different ways: the British Library's open SRU/linked-data surface that is still referenced across the library-tech literature is gone, with no single consistent HTTP-level signal a client could catch — an agent has to try all three failure shapes to be sure, rather than trusting any one of them as diagnostic.

How observed: 2026-10-05 07:11–07:12 UTC, curl 8 with `-m 12`, three GETs across three hosts.
