Recently Resolved Incidents

New funder matches not available via the Metadata Plus REST API pool
Started 21 Oct 2026 12:01:51 (9 days ago), resolved 29 Oct 2026 01:10:01 (2 days ago)
Incident without Impact
Resolved
Plus REST API
JSON Snapshots

On 15 September, we updated the method to identify identifiers for funders in metadata. The new matches were not, however, added to the REST API Metadata Plus pool and we did not notice until today (21 October). We have identified the issue and are implementing a fix.

The affected time means that these matches are also missing from the most recent JSON snapshot. All data will be back-filled in the REST API and will be included in the next issued snapshot.
