Keep Your Enterprise Running No Matter What

This post is a quick response from Scott Higgins, Senior Director of Engineering at Dispersive, following the recent AWS US-East-1 outage. The incident serves as a powerful reminder of why network resiliency and architectural redundancy matter more than ever.
On October 20, 2025, the Amazon Web Services (AWS) US-East-1 region suffered a major outage that rippled across the globe. Cloud applications slowed or went dark. Social platforms, consumer apps, collaboration tools, and enterprise workloads were all affected.
The root cause? A failure in AWS's internal load-balancer health checks and endpoint handling. But the impact went far beyond a single region-it cascaded through dependent services worldwide, underscoring just how interconnected today's digital infrastructure has become.
