Postmortem

Incident Summary

On August 25, 2025, starting at approximately 8:56 AM MT, some users may have experienced intermittent errors or slow performance when accessing the Impact service. Our engineering teams immediately began investigating the issue. The service was stabilized later that day, and a full resolution was implemented by August 26, 2025, at 3:32 AM MT. We sincerely apologize for any disruption this may have caused.

Timeline of Events

  • August 25, 8:56 AM MT (Investigating): We detected a service disruption affecting the Impact application. Our automated monitoring alerted our on-call engineering team, who began an immediate investigation.
  • August 25, 9:09 AM MT (Identified): The engineering team identified the source of the issue as an unexpected and significant increase in load on one of our core database systems.
  • August 25, 3:29 PM MT (Mitigated): A fix was deployed to stabilize the platform. At this point, service performance began to return to normal for affected users.
  • August 26, 3:32 AM MT (Resolved): After a period of monitoring to ensure stability, the incident was declared fully resolved.

What Happened?

A sudden surge in processing load on a core database caused a system-wide slowdown. This resulted in the intermittent errors and degraded performance that some of our customers experienced. Our investigation confirmed that this was not a result of any external factors or a security-related event.

Resolution and Recovery

To resolve the issue, our team took the following steps:

  1. Immediate Mitigation: We first took action to reduce the immediate load on the affected database, which quickly restored service stability.
  2. System Enhancements: To prevent recurrence, we have since increased the capacity of our backend systems to better handle unexpected processing loads.
