Chrome Connectivity Diagnostics is a fast and simple network testing and troubleshooting tool for Chrome and Chrome OS. The tool tests a computer's network connection for common issues, port blocking, and network latency by establishing connections to network and Internet services via UDP, TCP, HTTP and HTTPS.
