Sumo Logic Outage History

The Sumo Logic Authentication / Canada (CA) component underwent a scheduled maintenance window from 4:00 AM UTC to 6:00 AM UTC UTC. This maintenance was a rescheduling of an earlier window (originally planned for October 31, 2025), and during the window authentication-related services in Canada were placed in maintenance. The incident was limited to this component and completed without reported action required by users.

Two official updates were issued on the status page, reflecting the rescheduled maintenance and the successful return of the component to normal operation. The Canada Authentication component transitioned out of maintenance and was reported as up at 6:00 AM UTC UTC, marking the end of the two-hour window. This was a planned, targeted maintenance with minimal impact beyond the maintenance period.

Sumo Logic experienced latency in the CSE Processing Pipeline starting Nov 3, 2025 4:20 PM UTC, causing degraded performance in processing and displaying security data and affecting users in the North America US2 region. The issue progressed into a maintenance window at Nov 3, 2025 9:30 PM UTC, during which some users could be unexpectedly logged out of the Sumo UI. Regional maintenance followed for Europe 2 (DE) at Nov 3, 2025 10:00 PM UTC and Korea (KR) at Nov 3, 2025 11:00 PM UTC, with DE returning to normal by Nov 4, 2025 12:00 AM UTC. The provider published 6 status updates over the course of the incident and noted that no data loss was expected. Overall, the impact was regional, affecting 3 components across US2, KR, and DE rather than a global outage.

The CSE Processing Pipeline in the North America 2 (US2) region experienced latency in processing and displaying security data, resulting in degraded performance for users relying on security data workflows. The incident began at 10:05 AM UTC and lasted approximately 4 hours and 35 minutes, with the component listed as degraded during the event.

The provider issued two official status updates during the incident, first noting ongoing investigation into the latency and later confirming resolution as the CSE Processing Pipeline returned to normal at 2:40 PM UTC.

During a scheduled maintenance window, the Authentication / America Federal (FED) component was taken offline from 4:00 AM UTC to 6:00 AM UTC. Users may have been unexpectedly logged out of the Sumo Logic UI during this period; re-login could be performed immediately and no data loss was expected. The maintenance was limited to the Authentication / America Federal (FED) component and did not indicate a broader service outage. The provider issued 2 status updates documenting the start and end of the maintenance. The service returned to normal after 6:00 AM UTC with full recovery confirmed on the status page.

Sumo Logic conducted a scheduled maintenance window affecting the Authentication component in Canada. The window ran from Oct 31, 2025 4:00 AM UTC to Oct 31, 2025 6:00 AM UTC. During this period, users may have been logged out of the Sumo UI; logging back in generally resumes normal operation. No data loss is expected, and no action is required after the window. The status page noted that updates would be posted when maintenance is complete.

Sumo Logic experienced a brief degraded performance affecting Logs Collection and Cloud Collection in the North America 2 (US2) region. Users may have seen latency when processing and displaying logs, metrics, and traces, as well as delays in retrieving data from the cloud. The issue began at Oct 30, 2025 10:35 PM UTC and was resolved by Oct 30, 2025 10:50 PM UTC after about 15 minutes. The affected components were Logs Collection / North America 2 (US2) and Cloud Collection / North America 2 (US2).

Sumo Logic carried out a scheduled maintenance window from 4:00 AM UTC to 7:00 AM UTC. During this period, various functions of the platform were unavailable or experienced processing delays. Access to Cloud SOAR Automation was limited, and CSOAR and Automation Service operated with partial availability. Users attempting to run playbooks or actions that rely on the Automation Bridge could encounter interruptions. No data loss is expected and no user action is required after the maintenance window.

During a scheduled maintenance window, Sumo Logic's CSOAR and Automation services in Europe experienced partial disruption. The maintenance began on Oct 27, 2025 10:00 PM UTC and was resolved by Oct 28, 2025 12:00 AM UTC, lasting roughly 2 hours. Users in Europe 1 (EU) and Europe 2 (DE) may have seen limited CSOAR UI and Automation Service access, with potential delays for playbooks and actions relying on Automation Bridge. No data loss is expected. The affected components were Automation Service / Europe 1 (EU), CSOAR User Interface / Europe 1 (EU), Automation Service / Europe 2 (DE), and CSOAR User Interface / Europe 2 (DE). The incident involved 2 status updates during its course.

Sumo Logic experienced a regional outage beginning at Oct 20, 2025 7:35 AM UTC that disrupted Tracing Collection, Authentication, Billing and Account Management, CSE Processing Pipeline, and CSE APIs. Users reported login failures, latency in processing and displaying tracing data, and delays in security data and API communication. The issue widened as the underlying AWS us-east-1 region outage affected additional Sumo Logic services across multiple components.

Throughout the day, Sumo Logic documented ongoing recovery efforts via its status page, identifying the AWS us-east-1 outage as the root cause and providing frequent updates as services degraded and then gradually recovered. The incident unfolded in waves across regions, with some components returning to up in stages and others remaining degraded for extended periods. A scheduled maintenance window was announced, which could cause partial unavailability of certain functions, followed by partial recovery in the late hours.

By around Oct 20, 2025 10:20 PM UTC, several core data ingestion and search components had returned to up in select regions, signaling partial recovery, while other services continued to experience intermittent issues. Ongoing monitoring was advised as the environment stabilized.

The scheduled maintenance window for Sumo Logic began at Oct 19, 2025 5:00 AM UTC and ended at Oct 19, 2025 7:00 AM UTC. During this window, CSOAR User Interface / North America 1 (US1) and Automation Service / North America 1 (US1) experienced partial unavailability, and users attempting to run playbooks or actions via the Automation Bridge may have faced delays or failures. No data loss is expected, and services were restored after the maintenance concluded. The incident included two official status updates noting the maintenance and restoration.
