Minor August 20, 2025 Indexing services outage 16h 27m REST API, Fabrica, OAI-PMH, GraphQL API and 1 more
Started Aug 20, 2025, 12:44 PM UTC· resolved Aug 21, 2025, 05:11 AM UTC
- 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.
- 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.
- 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.
- resolved Aug 21, 2025, 05:11 AM UTC
All systems are operational and data unavailable in search index has been restored.
Critical July 17, 2025 DataCite homepage temporarily unavailable 1h 26m Homepage
Started Jul 17, 2025, 01:55 PM UTC· resolved Jul 17, 2025, 03:21 PM UTC
- identified Jul 17, 2025, 01:55 PM UTC
We've identified an issue that may affect access to the DataCite homepage at https://datacite.org and the Make Data Count homepage at https://makedatacount.org. Other DataCite services and APIs are not affected. The issue has been isolated, and we are working on a resolution.
- resolved Jul 17, 2025, 03:21 PM UTC
The DataCite homepage at https://datacite.org and the Make Data Count homepage at https://makedatacount.org are now available. We will continue to monitor.
Minor July 8, 2025 Test DOI Indexing and related services is unavailable on test systems 20m Metadata Store (MDS) API Test, REST API Test, Fabrica Test
Started Jul 08, 2025, 04:37 PM UTC· resolved Jul 08, 2025, 04:58 PM UTC
- 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.
- resolved Jul 08, 2025, 04:58 PM UTC
Test services are restored.
Notice June 18, 2025 Minor outage of background message systems 30m
Started Jun 18, 2025, 09:30 AM UTC· resolved Jun 18, 2025, 10:00 AM UTC
- resolved Jun 18, 2025, 11:33 AM UTC
Around 09:30 UTC to 10:00 UTC we had a minor outage within part of our infrastructure that processes various messages on queues (AWS SQS). This mostly meant that messages that usually processes tasks like indexing into our search cluster may have gone missing, this namely would affect things like DOI updates appearing in Commons/Fabrica public APIs. No data loss occurred as all data is saved to our database before background messages are sent to queues for processing. Users may have noticed http 500 (Internal Server Error) responses from our API endpoints during this period of time, but again the data was saved for any DOI create/update requests, it is also safe to re-run any requests that received these errors. The main issue that has arisen is some inconsistencies for a small amount of DOIs in our search index and possibly some URL updates to the global handle service that haven't gone through yet. We are working to clean up any inconsistencies, this should be complete within the next few hours.
Minor December 16, 2024 Service slowness and occasional errors 17h 25m REST API, Fabrica, OAI-PMH, GraphQL API and 1 more
Started Dec 16, 2024, 07:28 PM UTC· resolved Dec 17, 2024, 12:54 PM UTC
- 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.
- 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.
- resolved Dec 17, 2024, 12:54 PM UTC
This incident has been resolved.
Major October 31, 2024 Service slowness 14h 24m REST API, Fabrica, OAI-PMH, GraphQL API and 1 more

We're currently experiencing increased load on our services, we're investigating mitigation strategies. This mostly appears to be affecting our search cluster. Registration services should be unaffected, though may experience timeouts viewing content through frontend services / api search interfaces.
- investigating Oct 31, 2024, 04:47 PM UTC
We are continuing to investigate this issue.
- monitoring Oct 31, 2024, 05:21 PM UTC
Services appear stable, we will continue monitoring.

Minor October 30, 2024 Search cluster slow affecting multiple services. 20h 30m REST API, OAI-PMH, GraphQL API, Commons
Started Oct 30, 2024, 12:27 PM UTC· resolved Oct 31, 2024, 08:58 AM UTC
- investigating Oct 30, 2024, 12:27 PM UTC
We've noticed an increase load on our services which is having an affect on returning search results in different places. We are investigating possible causes and attempting to compensate.
- resolved Oct 31, 2024, 08:58 AM UTC
Yesterday we made some changes to how traffic was handled by our services, this combined with overall load reducing, everything should be working as normal now.
