Incident affecting Google Calendar

Incident began at 2022-05-03 19:12 and ended at 2022-05-03 21:24 (times are in Coordinated Universal Time (UTC)).

Date	Time	Description
May 10, 2022	8:06 p.m. UTC	INCIDENT REPORT SUMMARY: On Tuesday, 3 May 2022 12:12 US/Pacific, Google Calendar experienced issues importing trips data from Gmail for a duration of 2 hours 12 minutes. Calendar events could not be created from processing the user’s email that contained trip data. We apologize to the customers whose trip data was not added to their Calendar due to this issue. We completed an internal investigation and are taking immediate steps to improve the underlying system that caused the issue and prevent the issue in the future. ROOT CAUSE: An investigation into this incident revealed that a recent configuration change to an upstream data processing workflow triggered a new, unguarded code path, which caused internal errors in server-client communications. As a result, the trip data processing and creation transactions were disrupted and failed to complete the calendar event creation. The unprocessed trip data is automatically reprocessed by Gmail and hence the impact was limited to a delay in creation of calendar events for affected Gmail users. REMEDIATION AND PREVENTION: On receiving the alert for the issue, Google engineers started a backfill processing job to commence processing of Calendar trip data backlog and immediately rolled back the configuration changes that caused the issue. The rollback of the changes resolved the issues for all Gmail users and restored the trip data email processing feature on 03 May 2022 at 14:24 US/Pacific. Google engineers have taken the following steps to prevent the issue in the future: A code enhancement has been deployed to guard against use of new code paths, mitigating the server error observed and preventing further data processing from being interrupted. Additional checks are being added to configuration changes to ensure similar problems are caught before deployment. We apologize for the length and severity of this incident. We are taking immediate steps to prevent recurrence of this issue in the future.
