ACME Technologies Outage History

The immediate issue has been resolved, and we understand the disruption this caused for customers this morning. We have identified the underlying infrastructure issue and are already putting additional safeguards in place to strengthen system reliability and help prevent this type of issue from happening again. We are also improving the client \(POS\) experience during service degradation so any future issues are handled more gracefully.

### Issue Summary AWS identified a degradation in the underlying hardware supporting one of our production load balancer instances. While AWS had scheduled automated maintenance to address this, the instance became unavailable earlier than the maintenance window and stopped handling traffic. ### Impact Traffic routing through this load balancer was disrupted while the instance was in an unexpected state. ### Root Cause The issue was caused by degradation of the AWS host hardware. Additionally, our monitoring did not immediately alert on the instance becoming unavailable due to a configuration gap in our monitoring coverage. ### Resolution The affected instance was restored once AWS completed the stop/start process required to move it off the degraded hardware, and normal traffic handling resumed. ### Preventive Actions We are updating our monitoring configuration to ensure all critical production components are actively monitored and alerted on, reducing time to detection for similar issues in the future.
