Investigating - We reverted additional code earlier today during our weekly release in an attempt to pinpoint the origin of the performance lags in the submission and query queues at doi.crossref.org. Unfortunately, this did not result in a return to the processing speeds that we saw prior to 18 March. We have enabled additional processing threads for submissions and queries and continue to investigate the source of the lags. -IF

Monitoring - We have observed slower processing times in our submission queue - doi.crossref.org - during the last few days. We've exceeded 50,000+ pending submissions at the moment. We're still processing your submissions. We're hopeful that today's deployment will fix the performance lags. We're monitoring the issue. -IF
