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.
