30 June - maintenance, release v0.126.0
Completed - The scheduled maintenance has been completed.
Jun 30, 14:57 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Jun 30, 14:00 UTC
Scheduled - We will be undergoing scheduled maintenance - release v0.126.0 - on Thursday, 30 June from 1400 to 1600 UTC to correct the error we found where references registered with us were not being treated as open metadata (https://status.crossref.org/incidents/9q0yhqs5g21w). Our members may experience delays in deposit system admin tool (doi.crossref.org) processing. Deposits submitted during this time will be stored and processed after the maintenance has been completed.

Reference visibility in the REST API has reverted - all references should be set to open
Resolved - We've confirmed that the changes we have made so that all references registered with us are treated as open metadata are accurately reflected in the REST API again, so we're closing this incident.
Jun 30, 07:36 UTC
Monitoring - A fix has been implemented. We're going to leave this incident open until tomorrow so we can continue to monitor, and then confirm that the changes we have made so that all references registered with us are treated as open metadata are accurately reflected in the REST API.
Jun 29, 17:34 UTC
Identified - The issue has been identified and a fix is being implemented.
Jun 29, 17:25 UTC
Investigating - We recently announced that all references registered with us would be treated as open metadata (https://www.crossref.org/blog/amendments-to-membership-terms-to-open-reference-distribution-and-include-uk-jurisdiction/). It appears that change has been reverted in our REST API, and, thus, not all of references are being treated as open metadata. We're currently investigating.
