DOI registrations delayed a few hours

The last few days some large-scale processing has been taking place in EZID, with the result that DOI registrations have been delayed up to 8 hours.  We have adjusted the procesing to impact end users no more than a few minutes.

As a reminder, DOI registration backlogs may occur at any time.  This is due to the twin facts that EZID queues DOI operations for background processing, and that EZID operates much faster than the DataCite and Handle systems it interacts with.
