From Tuesday, April 21, 2026, at approximately 18:21 \(UTC\), to Thursday, April 23, 2026, at approximately 12:12 \(UTC\), some customers experienced intermittent connectivity and slow performance when using the Protect console in the US region. This issue was caused by unusually high traffic, which led to system unresponsiveness and latency for affected services. To resolve this issue, we performed system restarts, adjusted our resource distribution, and increased our network capacity to accommodate the traffic. Performance for the region stabilized on April 22, and Protect returned to normal performance by approximately 12:12 \(UTC\) on April 23, 2026. To prevent this type of issue in the future, we are implementing new automated alerts to identify high traffic more quickly. We have also permanently increased our network capacity to handle high traffic loads better. Finally, we have improved our system upgrade process to reduce the required time to update. No data loss occurred as a result of this issue.
