On June 13 2023, from 6:49 PM UTC to June 14, 2023, 02:20 AM UTC, Atlassian customers using Jira Software, Jira Service Management, Jira Work Management, Confluence and Trello with services hosted in AWS us-east-1 region were impacted by Automation rule degradation. This event was triggered by an increased error rates and latencies for AWS Lambda function invocations in the us-east-1 region. Some other AWS services also experienced increased error rates and latencies as a result of degraded Lambda functions invocations. This incident was automatically detected by multiple monitoring systems within 6 minutes, paging on-call teams. Recovery of the affected AWS Lambda service began after 116 minutes at June 13th 8:45 PM UTC. Full recovery of all AWS services occurred at 10:37 PM UTC June 13th after the backlog of asynchronous Lambda events had been processed. Some Jira tenants with large event backlogs experienced delays in running schedule-based rule reruns. Full recovery of all Atlassian Cloud services was notified at June 14, 2023, 02:20 AM UTC.
The overall impact was between June 13, 2023, 06:49 PM UTC and June 14, 2023, 02:20 AM UTC. Product-specific impacts are listed below.
The service disruption lasted for 7 hours and 1 minutes between June 13, 2023, 06:49 PM UTC and June 14, 2023, 02:20 AM UTC and caused service disruption to customers with services hosted in the US-EAST-1 region.
Atlassian uses Amazon Web Services (AWS) as a cloud service provider. The root cause was an issue with a subsystem responsible for capacity management for AWS Lambda in US-EAST-1 Region, which also impacted 104 AWS services. This impacted Automation rules as the service is hosted exclusively in this region.
There were no relevant Atlassian-driven events in the lead-up that have been identified to cause or contribute to this incident.
