We experienced a service degradation with our market data streaming service on August 28, 2025. A recent deployment caused a bug that resulted in duplicate and incorrect market data being sent to some users. Our engineering team identified the issue and deployed a fix to resolve the problem. The service is now operating as expected, and we will continue to monitor the system to ensure stability.
