Identified - We discovered yesterday that some ~6,000 DOIs in the current Metadata Plus JSON snapshots (and within the REST API) are missing the memberID element. We're currently investigating a fix.
Jul 28, 14:24 UTC
Investigating - We’re still experiencing problems with load on the Event Data service. Users may see their queries time out when using the API. We’re investigating and will confirm when the issue is resolved.

Resolved - We discovered that our test admin tool (test.crossref.org) was being delayed by a couple of large submissions earlier today (19:00 UTC). We removed those submissions and restarted the admin tool. There are more than 20,000 existing test submissions in the queue, so it will take additional time for those submissions to be processed.

Identified - We discovered that the crm-items that we supplement to the Metadata Plus XML snapshots are missing from the most recent XML output. We're rebuilding the XML snapshots with the crm-items now and expect the full XML output will be available later this week. Note: these crm-items are still present in OAI-PMH and the transformed XML available via the REST API.

Resolved - Our partners at CNRI had trouble with the Crossref handle server starting at 20:00 UTC today. This caused deposit errors for some of our members that included this error message: "HandleException (CANNOT_CONNECT_TO_SERVER)." CNRI has fixed the error and we are reprocessing all failed submissions that were received since 20:00 UTC today.
