WMC intermittent page load issue

Incident Report for 14 West Product

Resolved

Hello,

Today we experienced connection issues affecting WMC. The issue has been resolved and services are operating normally.

What happened:
Database changes deployed to WMC today caused CPU usage on the database to reach its maximum, which overloaded the database and caused connection failures.

What customers saw:
Some customers would have experienced slow page load times or an error page, indicating either a 500 error or a custom error page.

Detection:
Our monitors alerted us to the issue, and the IT team was investigating as the affiliates and WMC team began noticing the impact.

Resolution:
We rolled back the changes immediately, after which CPU usage returned to normal and connectivity was restored.

Duration:
The incident lasted approximately 27 minutes (15:09 – 15:35 UTC) and affected approximately 50% of WMC traffic during this time.

Next steps:
The team is reviewing the changes to understand the performance impact and stabilize the necessary database changes.

Please reach out if you have any questions.

Thank you,
Sarah Smiley
