From Monday, September 28, 2026, at approximately 20:43 \(UTC\), to Friday, October 2, 2026, at approximately 10:24 \(UTC\), some customers experienced delayed mail flow and intermittent console access issues in US instances of Prevent and Protect. This issue was caused by a capacity limit in the network firewalls in front of our US mail-processing services. During peak traffic, the firewalls could not process connections fast enough, which caused internal requests between services to be delayed or time out. As a result, mail processing slowed, and messages queued. To resolve this issue, our team increased the capacity of the US firewalls. Prevent and Protect handled peak traffic without further issue and returned to normal performance by approximately 10:24 \(UTC\) on October 2, 2026. To prevent this type of issue in the future, we have expanded our firewall monitoring to track network health indicators in addition to compute use. We have also added logging to improve visibility into failed internal requests. No data loss occurred as a result of this issue.

From Thursday, September 24, 2026, at approximately 17:07 \(UTC\), to Friday, September 25, 2026, at approximately 09:16 \(UTC\), some customers experienced intermittent slowness, errors and delayed mail flow in US instances of Protect and Prevent. This issue was caused by an unusually large spike in email traffic. The increased volume placed a sustained load on our network services, which operated within fixed capacity limits. As a result, mail processing slowed, some internal requests failed, and messages queued. Our team monitored the affected systems while the elevated volume subsided and load returned to normal. Protect and Prevent returned to normal performance by approximately 09:16 \(UTC\) on September 25, 2026. To prevent this type of issue in the future, we are improving our monitoring of unusual increases in email volume. We’re also evaluating ways to scale our network capacity more dynamically during sudden traffic spikes. No data loss occurred as a result of this issue.

On Monday, September 21, 2026, from approximately 08:55 until Tuesday, September 22, 2026, at approximately 14:30 \(UTC\), some users experienced errors and were unable to send emails via Web Access \(Secure Message Portal\) in the UK region.  This incident was caused by a configuration error during a database update, which led to intermittent service disruption. To resolve this issue, we reverted the configuration, and Web Access returned to normal performance by 14:30 \(UTC\) on September 22, 2026. To prevent this type of issue in the future, we are reviewing and updating our database configuration.  No data loss occurred as a result of this issue.
