A major outage at Amazon Web Services' US-EAST-1 region in northern Virginia caused widespread internet disruptions on Monday morning, October 20, 2025. DNS resolution issues affected numerous platforms, including Amazon's own services and third-party apps. The incident highlighted vulnerabilities in cloud infrastructure.
Developers of the widely used BIND DNS software have warned of two high-severity vulnerabilities that could enable cache poisoning attacks, similar to those revealed in 2008. Unbound, another DNS resolver, faces a related flaw reported by the same researchers. Patches for all issues became available on October 22, 2025.
