There were 7 yasoon outages since February 5, 2026 totaling 935h 7m of downtime. Each is summarised below — incident details, duration, and resolution information.
For a few hours today, posting Microsoft Teams channel messages from the Jira UI or via an Automation rule resulted in timeouts or errors. The outage seems to be resolved now, but we are monitoring.
We have identified an incident where a subset of users will see error messages when trying to login with their Microsoft account. Upon investigation we discovered that Microsoft seems to be rolling out a set of changed browser headers which are causing issues. We are working on a fix - in the meantime, re-trying to login for a few times seems to solve the issue for most users.
Microsoft seems to have rolled back the change, we'll be monitoring and working on an implementation that works around this new header, should it roll out eventually.
We are currently investigating an incident where the Smart Connect for Jira app is not accessible in Microsoft Teams. From the first look of it, it seems that this is a Microsoft Teams issue, as the app continues to work on mobile. We have raised the issue with Microsoft. https://github.com/OfficeDev/microsoft-teams-library-js/issues/2982
We have identified an issue with the Microsoft Teams platform that affects apps on a certain feature/schema version. We are trying to fast-track an app update to a previous version which is apparently not affected by this bug. We are also trying to escalate the bug within Microsoft.
As far as we can tell, a fix on the Microsoft side was successful and the app can be used in Microsoft Teams again. We'll be monitoring in case the issue re-appears. Apologies for the interruption.
Yesterday we experienced a full service outage from approximately 8:30 PM CET until 22:45 PM CET, due to a spike in database usage in our main database. We'll do a full investigation and post a post-mortem soon.
We are currently seeing a bug affecting the Atlassian Forms API, regarding to the new conditional section logic. Please refrain from updating Forms until the bug is fixed, otherwise the conditions will not be evaluated correctly in our Microsoft Teams portal app.
We are in active contact with Atlassian to get the bug fixed as soon as possible, please refrain from updating your Forms, if possible, until this issue is resolved.
Atlassian is working on a fix for this issue, please let us know in case you are affected, Atlassian has the ability to roll back the change temporarily on a case by case basis.
We got an update from Atlassian engineering and they expect the bug to be fixed in "a weeks time". We'll update the incident accordingly once the fix is available.
A fix has been rolled out by Atlassian for the issue. The new conditional logic for Forms should now work inside the JSM portal inside teams. We apologize for the disruption!
We are in touch with Atlassian to resolve this degradation. Customers can see long running board load times with some board running into timeouts.
This seems to have resolved itself, although we do not have any any acknowledgement from from Atlassian on the issue. We'll continue to investigate.
We are seeing a re-occurrence of the issue that happened a few weeks ago. We are currently seeing an increased amount of errors in the chat functionality, coming from the Microsoft Graph API. We'll provide an update once we have more information.
We are continuing to work with Microsoft on the issue and hope to have an update soon. If you see errors when creating chats, please try to create the chat again. It's also possible that the chat is created in Teams, despite an error being shown in Jira.
We are seeing some improvements to this issue but are closely monitoring this. Still awaiting feedback from Microsoft on the issue.
We are continuing to monitor for any further issues.
This incident has been resolved on the Microsoft side, chats can now created normally again.
