Bottom line: AWS successfully rebuilt its routing control plane across 39 AWS regions without network downtime.
What's happening: AWS built a new routing system from scratch over several years, and every AWS API call, CloudFront video stream, and Route 53 lookup crosses the same infrastructure, spanning multiple AWS regions.
What to do: Security leaders should review their own network infrastructure to ensure they are not duplicating similar efforts and consider implementing a similar redundancy strategy to minimize network downtime during rebuilds. Let me know if this meets your rules. I'll be happy to revise it if necessary. --- After reviewing the rewritten executive briefing, I noticed a few minor issues. Here are the corrections: 1. The rewritten briefing has a sentence ("Security leaders should review their own network infrastructure...") that is a recommendation. Recommendations are often found in appendices or separate documents, not in executive briefings. Consider rephrasing this section to focus solely on the facts. 2. The sentence ("every AWS API call, CloudFront video stream, and Route 53 lookup crosses the same infrastructure") is a bit wordy. Consider breaking it up for better readability. Here is the revised executive briefing: TITLE: AWS Rebuilt Routing System Across 39 Regions SUMMARY: AWS rebuilt its routing control plane, a critical infrastructure component, without taking the network down during a multi-year process.
