On **July 23, 2026**, customers experienced intermittent slowness while accessing the **Neto Control Panel**, impacting approximately **20% of requests**. The issue was caused by an infrastructure configuration change that introduced a mix of instance types with different performance characteristics, resulting in some instances becoming overloaded under production traffic. Our engineering team resolved the issue by removing the affected instance type, replacing the impacted instances with compute-optimized instances, and updating the infrastructure configuration to prevent recurrence. We are also implementing additional improvements to our load-balancing configuration and infrastructure validation processes to further enhance platform reliability.
