Incident Report

Summary AI Generated

Cronofy experienced increased error rates when syncing with Google Calendar due to Google's API returning elevated 503 errors, affecting a small percentage of calendars and causing delayed syncs for some users. While the vast majority of events continued syncing almost immediately, a minority experienced delays of a few seconds during the 6.8-hour incident. The issue was resolved with Cronofy's systems maintaining correct event synchronization throughout, and normal sync performance was restored.

Events continue to sync events into Google Calendars as normal. We are still seeing an elevated number of errors between Cronofy and Google Calendar, but are confident that our system are keeping events in sync correctly.

The vast majority of events are still syncing almost immediately, while a minority of updates sync after a few seconds. This should have no impact on customers applications, so we are resolving the incident.

We will continue to monitor the situation and will raise a new incident if performance declines to a noticeable level.

We are continuing to see elevated errors when communicating with Google Calendar.
Cronofy is operating normally - event changes are still syncing correctly. The only impact is that some changes may take slightly longer to be reflected in Google Calendars than usual.

We are continuing to monitor the situation, but will only update this incident if there is a significant change in either direction.
