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
