Since approximately Tuesday June 24th, 18:35 UTC, we saw a much higher than normal number of errors when communicating with Apple's calendar service. Error returned to regular levels at around 23:00 UTC.
Sync with Apple calendars may have taken longer both to and from Apple as a result of the underlying errors during this period.

Update
We continue to see a much higher than normal number of errors when communicating with Apple's calendar service.
Our retry mechanisms appear to be doing their job, but changes to calendars may take longer to sync both to and from Apple as a result of the underlying errors.
We are still monitoring the situation
