AWS spent years rebuilding its routing control plane without taking the network down

AWS rebuilt its border network routing control plane from scratch over several years without downtime, managing traffic across 39 regions, 123 availability zones, and over 750 points of presence. The system directs all application programming interface (API) calls, CloudFront video streams, and Route 53 lookups while maintaining peering connections with more than 5,000 outside networks.

Why it matters: AWS customers rely on this routing infrastructure for all workloads; the successful rebuild demonstrates how hyperscalers manage large-scale infrastructure changes without service disruption, relevant to practitioners assessing cloud provider reliability.
