Monitoring
Identified - We are investigating an issue affecting user logins across Cognite Data Fusion (Fusion), Infield, and Maintain. Some users may experience login failures displaying the error: "An HTTP line is larger than 4096 bytes".
A recent identity service update has been identified as the likely cause, and our engineering team is actively deploying a rollback to restore full login functionality.
We will provide another update soon as the rollback is completed.
