Handle system recovery status

From DataCite, regarding the recent Handle System outages…

Minting and Updating is possible again. There shall be no errors any more.

However, there are still some syncing problems. Some DOIs registered in the last days might currently not be resolveable. CNRI is working on this:

| I can confirm, however, that not all transactions from the two former
| primaries of the past week were replicated at the current primary.
| I will be correcting this now.

After CNRI has fixed this we will run a full check to see if really all
recently registered DOIs are resolveable.
