Summary Our web application experienced performance issues on November 17, 2025 between 09:50 AM and 10:10 AM AEDT, due to elevated CPU usage caused by a surge in connection traffic. Users may have experienced slow page loads and connection timeouts during this period.
Root Cause A surge in SignalR reconnection attempts created elevated CPU load on our web servers, leading to degraded application performance.
Resolution Our team increased the number of servers to handle the traffic spike. System performance has been restored to normal levels.
Next Steps We'll continue monitoring for these connection patterns, and infrastructure scaling adjustments to prevent similar issues in the future and further optimise traffic. We apologise for any inconvenience and thank you for your patience.

An additional server has been added to the pool while the investigation continues. CPU levels have returned to normal and performance has stabilised. We will continue to monitor the environment and provide further updates if required.
