Summary
On October 20, 2025, portions of the ATS platform experienced intermittent instability as a result of the Amazon Web Services outage affecting one of our infrastructure providers. While the ATS remained generally operational throughout the incident, some background integrations and related services were temporarily degraded.
Impact
Most users were able to access and use the ATS web app and APIs during this event. However, some customers may have noticed occasional delays or minor interruptions in background processes, search indexing, or scheduled jobs. A small number of integrations experienced brief instability as connected services encountered related outages.
Resolution
Our team monitored the situation closely and confirmed that once our infrastructure provider resolved the underlying issue, ATS operations stabilized without requiring manual intervention. Any delayed background tasks were automatically retried and completed successfully.
Next Steps
We are continuing to review alerting and monitoring systems to improve response visibility during upstream service incidents.
