Monitoring - A fix has been implemented and we are monitoring the results.
Oct 15, 17:09 UTC
Investigating - We look to have stalled processing threads in the admin tool (doi.crossref.org) causing additional delays at the moment. We're investigating.
Oct 15, 14:20 UTC
Update - We have re-enabled the queue. Submissions are now processing. Yay! We continue to monitor the queue and your submissions.
Oct 13, 17:03 UTC
Update - We will be pausing the submission queue (doi.crossref.org) shortly to remove ~10,000 submissions that one of our members flagged as containing metadata errors. All submissions sent to us during this time will be stored and processed as soon as the erroneous submissions have been removed and the queue reactivated.
Oct 13, 16:32 UTC
Monitoring - A fixed has been implemented. Submissions are now processing in our admin tool (doi.crossref.org). We continue to monitor the results.
Oct 12, 20:43 UTC
Identified - The issue has been identified and a fix is being implemented.
Oct 12, 19:49 UTC
Investigating - We look to have stalled processing threads in the admin tool (doi.crossref.org) causing additional delays. We're investigating.
Oct 12, 19:16 UTC
Monitoring - Submission processing in the queue is in much better shape today than last week. We have ~27,000 pending submissions in the queue - as of this writing - compared to 75,000+ at several points last week. The current issue is that several users have very large file sizes for book registrations and reference list updates working their way through the queue (these larger submissions require more time for us to match references against and process). Given the logic in submission processing in the queue, those larger submissions are largely affecting other larger submissions. Instead of a general backlog, like we had last week, we currently have a backlog in submissions of very large file sizes. Thankfully, for members submitting smaller file sizes, you will likely not notice any significant lags in submission processing.
Oct 11, 19:35 UTC
Identified - Due to yesterday's outage - https://0-www-crossref-org.lib.rivier.edu/blog/outage-of-october-6-2021/ - we will need to reprocess all submissions that were processed between 1400 and 1900 UTC yesterday, 6 October. This will result in additional submissions into the queue, which is already delayed. We will be begin reprocessing these submissions imminently.
Oct 7, 17:14 UTC
Monitoring - A fix has been implemented and we are monitoring the results.
Oct 4, 18:16 UTC
Identified - The issue has been identified and a fix is being implemented.
Oct 4, 14:49 UTC
Investigating - Processing of submissions in the admin tool (doi.crossref.org) is slower than we would like today. We are storing all submissions sent to us and are processing them as fast as we can, but there is a noticeable backlog at the moment. We're investigating.

Scheduled - On 13 October, we will be making backend changes to our content negotiation service, effectively folding it into our REST API. While behavior should be unchanged for requests made according to the specification, there are a few functional changes to note.
1) The resolver URL will change from http://data.crossref.org to https://api.crossref.org
2) Content negotiation responses will be returned by one of our three API pools depending on whether you include mailto identification in your user agent header for the polite pool, or include a token for Metadata Plus subscribers accessing the Plus pool. All other requests will be serviced by the public pool.

Sep 24, 20:43 UTC
Monitoring - Event Data had a problem adding new events to the API yesterday, 23rd September, caused by a configuration bug. The collection of new events was delayed but it didn't affect the stability of the query API. A fix has been implemented and we are monitoring it over the next few hours. We expect all missing events to be added soon.
