Introduction​

On July 24, 2026, AWS lost connectivity between the us-west-2 (Oregon) region and the Seattle Metro. The initial impact window was 20 minutes for most and 1 hour 17 minutes for a few customers using AWS Direct Connect through EqSe2, Westin Building Exchange, Seattle. Any traffic that both started and ended inside the region kept working, whereas anything crossing the region boundary saw timeouts and errors. This included the AWS Management Console for some customers.

Downstream services took longer to recover. IncidentHub recorded 9 confirmed cascade incidents across 7 providers, and 3 possible cascade events at 3 more.

On July 16, 2026, AWS experienced a disruption in its CloudFront service, which affected a large number of websites and applications. The outage was caused by a configuration loading failure in CloudFront's VPC Origins feature. This was AWS's most widely-felt outage after last year's outage on October 20th, which caused widespread damage.

Introduction​

Amazon Web Services remains one of the most popular cloud providers, with 200+ services in 39 regions across the world. Like all providers, they have their share of outages.

In 2025, IncidentHub detected 38 AWS outages, of which the one on October 20th had the most widespread impact affecting hundreds of SaaS providers simultaneously. Payments were disrupted, students lost access to classrooms, developer tooling degraded, and some IT teams experienced alerting gaps.

In this post we look at the reliability of AWS in 2025 based on their own publicly available status page data aggregated by IncidentHub, with a deeper analysis of the cascading impact of the October 20th outage.
