Events failing to sync to user calendars
Resolved - At approximately 12:30 UTC a change was released that prevented events being created in Microsoft calendars if integrated conferencing was being used.

A fix was released and the last error observed at approximately 16:05 UTC.

Over 90% of the impacted events were successfully synced due to standard retry mechanisms with the platform by 17:00 UTC, we also ran a sweep to proactively retry all remaining events which completed by 17:30 UTC.

This incident is now resolved and operations are back to normal.

We will be conducting a postmortem and will publish the findings of that next week.

Elevated API 500 errors in our AU data center
Resolved - Between 12:52 and 12:55 we saw that calls to our API encountered a higher level of 500 Server Error responses than usual

We have investigated this and it appears to relate to a period where we saw a large spike in traffic, a rapid drop and another spike in quick succession resulting in some temporary 500 errors.

This is now resolved but we will continue monitoring for any further issues.
