postmortem May 15, 2026, 02:44 PM UTC

On Friday, May 8, 2026, from approximately 01:45 to 03:08 \(UTC\), some US customers experienced issues accessing the PhishER console and PasswordIQ. This incident was caused by a localized infrastructure failure at our cloud service provider, which affected authentication traffic and prevented login verifications. To resolve this issue, we reprovisioned our authentication resources to healthy environments. After we rerouted login traffic to the healthy environments, PhishER and PasswordIQ returned to regular performance by 03:08 \(UTC\). No data loss occurred as a result of this issue.
