Amazon VPC Reachability Analyzer now supports network reachability analysis between AWS resources across different AWS accounts in your AWS Organization, allowing you to trace and troubleshoot the network reachability across your AWS Organization.
VPC Reachability Analyzer allows you to diagnose network reachability between a source resource and a destination resource in your virtual private clouds (VPCs) by analyzing your network configurations. Previously, you could only use Reachability Analyzer to analyze network reachability between AWS resources that were within the same AWS account. With the AWS Organizations support for Reachability Analyzer, you can now view the hop-by-hop details of the virtual network path between your specified source and destination across multiple AWS accounts in your AWS Organization, and also isolate network configuration issues that could be blocking network reachability between them. For example, Reachability Analyzer can help you identify a missing route table entry in your VPC route table that could be blocking network reachability between an EC2 instance in Account A that is not able to connect to another EC2 instance in Account B in your AWS Organization.
