Elevated Error Rate on DeepL SSO

Incident Report for DeepL

Postmortem

We have migrated our SSO service to a new system to improve performance. During this process, some users experienced problems logging in due to outdated connection records being cached.

We quickly resolved the issue by updating our systems to support both the old and new configurations, ensuring that all users were able to access the service.

To prevent this from happening again, we will improve the way we handle system changes and monitor connection updates more closely.

We apologize for any inconvenience and thank you for your patience.
