Timeline · 4 updates
  1. investigating Aug 20, 2025, 12:44 PM UTC

    We're experiencing some timeouts adding to our search index cluster, this will mostly be noticeable in DOIs that are registered might not be findable via certain API endpoints and search/management interfaces. We believe this is a disk space issue due to increased demand and are investigating a remedy. Note no actual data loss as this is just the indexing side, data storage is unaffected and therefore DOI registration is operational.

  2. identified Aug 20, 2025, 01:55 PM UTC

    A temporary fix has been put in place and things should be working now, but we may still have a period of time where some things have not been indexed. We are working on a longer term fix for increased demand and also add any missing items (i.e. DOIs) to our search indices.

  3. monitoring Aug 20, 2025, 02:47 PM UTC

    We've added a further fix and all search indexing and related services should be operational. We are now monitoring and looking to clean up any missing data in the indices.

  4. resolved Aug 21, 2025, 05:11 AM UTC

    All systems are operational and data unavailable in search index has been restored.

  1. identified Jul 08, 2025, 04:37 PM UTC

    The test services that are powered by our OpenSearch cluster are currently not accepting new index writes. This means data is still being saved to the test database, but new records and record updates (for DOIs, members, repositories, etc.) are not appearing in REST API list responses, Fabrica list views, and other places that rely on the OpenSearch index We believe we already know the issue but are currently discussing about how best to resolve. Production services are not affected and are operating as normal.

  2. resolved Jul 08, 2025, 04:58 PM UTC

    Test services are restored.

Duration

Affected: REST APIFabricaOAI-PMHGraphQL APICommons
Timeline · 3 updates
  1. investigating Dec 16, 2024, 07:28 PM UTC

    We're currently experiencing increased load on our services and are investigating the underlying cause and mitigation that we can take. This mostly appears to be affecting our search cluster, and therefore has a knock-on effect to queries and retrieval through DataCite Commons and some functionality in Fabrica. DOI Registration services should be unaffected, although may experience timeouts viewing content after registration.

  2. monitoring Dec 17, 2024, 09:56 AM UTC

    Mitigation strategies have been deployed to help with some anonymous traffic that was causing increased load on our search cluster. Services appear to be resuming normal function but with potentially still some degraded performance, we will continue monitoring.

  3. resolved Dec 17, 2024, 12:54 PM UTC

    This incident has been resolved.
