   # 2026-04-14 SEV1 Incident Postmortem - Hosted Service in the US experiencing high latency and errors # Incident Postmortem - Elevated Application Error **Date of Incident:** 2026-04-14 **Time of Incident \(UTC\):** 17:25 - 18:00 **Service\(s\) Affected:** Sign in, Admin console **Impact Duration:** Approximately 35 minutes ## Summary On April 14, 2026, [1Password.com](http://1Password.com) experienced elevated error rates due to an increase in traffic to our USA/Global infrastructure. Requests arrived more quickly than they could be serviced in our USA/global region. Customers experienced errors and high latency. This was not a security incident, and there was no loss of data. ## Impact on Customers * **Sign-in and account access:** Some customers in the USA/Global region experienced errors when attempting to sign in or access their 1Password accounts between 17:25 and 18:00 UTC on April 14, 2026. * **All 1Password clients:** The disruption applied to all client types, including the web app, browser extensions, and desktop and mobile applications, for customers connecting through the USA/Global region. * **Number of affected requests:** Approximately 2.95% of requests over the incident window to [1Password.com](http://1Password.com) \(USA/Global\) during the incident window resulted in errors or timeouts, though for some brief spikes up to 45% of requests failed. * **Geographic regions affected:** Customers on our USA/Global only, other regions were not affected. ## What Happened? An unusually high volume of traffic exceeded the capacity of our controls, and triggered latency and errors in the underlying applications. * **Timeline of events:** * **2026-04-14 17:25** - Start of incident. * **2026-04-14 17:36** - Issue identified. * **2026-04-14 17:51** - Fix implemented. * **2026-04-14 18:01** - Recovery complete. * **Root cause analysis:** An increase in traffic exceeded the capacity of our traffic management layer, causing degraded service for customers in the USA/Global region. ## How Was It Resolved? * Established runbooks for load shedding and system upgrades mitigated the issue. ## What We Are Doing to Prevent Future Incidents * **Resolution:** We made two key changes to prevent recurrence: 1. **Increased capacity of internal systems** 2. **Upgraded traffic controls at the network edge** * **Verification:** Since implementing these changes, we have observed several additional instances of unusually high traffic matching this incident. In each case, the new controls handled the traffic automatically with no impact to customers or our systems. ## Next Steps and Communication * No action is required from our customers at this time. We are committed to providing a reliable and stable service, and we are taking the necessary steps to learn from this event and prevent it from happening again. Thank you for your understanding. Sincerely, The 1Password Team
