Incident Summary:
On the morning of December 6, 2024, users attempting to log into the Hayylo platform via Single Sign-On (SSO) experienced login failures.

Root Cause:
The issue was caused by an infrastructure change that introduced a logging directory permission error. This error prevented the SSO login service from functioning correctly.

Resolution:
Once identified, the team corrected the directory permissions, restoring functionality to the SSO login process. The issue was resolved at approximately 8:10am for all users, and affected users were informed of the resolution.

Preventive Measures:
We are taking the following actions to prevent similar issues in the future:

1. Implementing additional automated testing and validation during infrastructure changes.
2. Strengthening logging and alerting to quickly detect and isolate permission-related issues.
3. Updating deployment processes to include directory permission checks as part of standard procedures.

We apologise for any inconvenience this incident may have caused and appreciate your understanding.
