An unknown number of users found browser crashes when browsing through the Learn section of Fluid Attacks' web page (at UTC-5 23-11-08 09:50 to 23-11-08 16:35 | Time to recover was 57.6 minutes). The incident was discovered proactively (at UTC-5 23-11-08 15:36 | Time to detect was 5.7 hours) by an engineer of the product team who was auditing the Learn section on the web page.
The component responsible for displaying the information posts in this section entered a continuous rendering loop due to an element in the wrong place in the code . This continuous rendering hurt the performance of web browsers, leading to resource consumption and browser crashes.
The developer in charge reverted the changes made to the component, returning resource consumption to normal and restoring the common browser experience for this website .
A linter should have identified the incorrectly positioned element, but it went unnoticed. The team is actively reviewing these tools to address this type of oversight before reaching the production stage. PERFORMANCE_ERROR < FAILED_LINTER
