Apple calendar sync degraded
Resolved - Starting at 10:40 UTC we observed an elevated error rate when communicating with Apple's calendar service. Errors returned to regular levels by 11:35 UTC.

Sync with Apple calendars may have taken longer both to and from Apple as a result of the underlying errors during this period.
Sep 15, 11:49 UTC
Monitoring - Since 10:40 UTC we have observed an increased error rate for Apple calendar sync operations. We are still seeing more successes than failures but consider there to be enough failures to mark Apple as degraded.

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 monitoring the situation.
