HTTP 500 error when accessing Jira site.

Impact
Some customers are experiencing HTTP 500 errors when accessing their Jira Service Management, Jira Software, and Jira Work Management sites.

The impact to the developer platform was limited to Jira apps or apps that integrate with the Jira Cloud API with active installations on sites in the US region. As this incident impacted the availability of Jira itself, Jira apps were also unavailable. For non-jira apps running in the affected region, any calls made to the Jira Cloud API would have received HTTP 500 responses during the incident timeframe.
