Route 53 Resolver Goes Live on AWS Outposts—Local DNS Without the Latency
Amazon Route 53 Resolver is now generally available on second-generation AWS Outposts, letting you resolve DNS queries locally without hitting the parent region. This means faster lookups, zero Service Link dependency, and built-in caching that keeps things running even during connectivity hiccups—all on AWS-managed infrastructure.
