Incident Report: Temporary XML Service Disruption on November 20

On November 20th, our XML service experienced a temporary disruption, resulting in HTTP 500 errors, which prevented users from accessing the necessary data through our platform.

What Happened?

In our latest release, we updated the Presentation value calculation logic. Unfortunately, this change introduced an unexpected error in the XML output processing, resulting in the service returning HTTP 500 responses.

How We Responded

Our monitoring system immediately detected the issue and alerted our development team.

Our specialists quickly investigated, identified the root cause, and implemented a fix.

By noon on November 20th, the XML service was fully restored and functioning normally.

Moving Forward

We sincerely apologize for the inconvenience this incident has caused.

We understand how critical our XML services are for your daily operations, and we are committed to ensuring their stability and reliability.

To prevent similar issues in the future, we have already:

• Introduced stricter validation rules at the code review stage to detect and prevent such issues before deployment.
• Updated our approach to data validation for output files, ensuring that any inconsistencies do not impact the service.

Thank you for your understanding and continued trust.
