Service Disruption on October 20, 2025

Original post: Service Disruption on October 20, 2025

This is a post-mortem from incident.io about an incident originating from the AWS outage in the us-east-1 region.

I wanted to share this here because it made me realize something I hadn’t properly thought about before: when half of the internet is down, services like incident.io or Pagerduty experience a huge increased load because everyone relies on them to get notified when their system is down.

That’s an inception thing 😄
