Update - We are continuing to investigate this issue.
Oct 07, 2024 - 15:26 UTC
Investigating - There is a bug in the code that generates the new XML Metadata Plus snapshots and, as a result, this month's XML Metadata Plus snapshots will be delayed. We are working to update that code so we can generate the most recent XML Metadata Plus snapshots. -IF
Oct 04, 2024 - 15:57 UTC
Update - The browsable title list - https://www.crossref.org/titleList/ - is now available. We're still working to fully restore a few other reports/tools: refreshing the data within the conflict reports and the PubMed IDs search functionality in the Simple Text Query form. -IF
Oct 01, 2024 - 14:08 UTC
Update - Our technical team has fixed the issues with submission log emails. All members should now be receiving submission log emails for their submissions. In addition, our team has fixed depositor reports (for journals, books, and series).

Sep 23, 2024 - 18:27 UTC
Update - We are continuing to work to fully restore all of our reports (e.g., browsable title list, conflict reports, depositor reports). In addition, we have identified errors with submission logs being sent as a result of your deposits. These errors are also related to our database migration earlier this week.

We are still processing your deposits. Submission processing is not broken; it is only the missing emails that are an issue. We are working to fix the bug resulting in missing emailed submission logs. As an alternative, you can always use our admin tool to review your recent submissions. Follow these directions: https://www.crossref.org/documentation/register-maintain-records/verify-your-registration/submission-queue-and-log/#00143 -IF

Sep 20, 2024 - 16:05 UTC
Identified - As a result of our database migration - https://status.crossref.org/incidents/v3k2t9f3jdcw - some of our reports (e.g., browsable title list, conflict reports, depositor reports) have not yet been fully restored. Our technical team is working to fully restore those reports now.
