Since 2 April Event Data has not been adding new events to Event Data. We have determined the problems and are starting to implement a fix. All missing events will be recovered, although it may take several days to fully catch up. We apologise for any inconvenience and will update here when the issue has been fully resolved. You can track the fix at https://crossref.atlassian.net/browse/CR-1821
We have fixed the bug causing this issue and new events are being added. We are still in the process of catching up, but expect it to be complete with in the coming two or three days.
Some of the missing events were recovered but the issue has reoccurred. We will continue to look into it, however it is likely to be next week before it can be fully resolved.
