Issues with logging in and saving changes

All reported issues have now been resolved. Both the initial outage and the subsequent issues affecting certain actions (switching accounts, editing jobs, adding comments) have been addressed; these were caused by a stale login cookie. If you continue to experience problems, please log out and log back in to resolve this.

Thank you for your patience while we worked to resolve this issue.

Service Restored, Continued Monitoring.
The ATS was unavailable for approximately 20–30 minutes. We've identified the cause: a malfunction in an email delivery notification system created excessive traffic to our servers, degrading performance. We've disabled the affected component and service has been restored.
We are continuing to investigate a related issue affecting some data-saving actions and will provide a further update shortly.

We're aware that some customers are experiencing issues logging in, switching accounts, and saving or editing changes in the ATS. Our team is actively investigating the cause and working on a fix. We'll post an update as soon as we have more information.
