ネットワーク接続をテストし、レイテンシを測定し、サーバーの可用性を即座に監視 by AIO.com.ai

This extension requires host permissions to send HTTP HEAD requests to user-specified target URLs for connectivity testing. The technical implementation uses the Fetch API to measure server response times and verify endpoint reachability. Users manually input the URL or IP they wish to test, and the extension performs HEAD requests to that specific destination. Without broad host permissions, the extension cannot fulfill requests to arbitrary user-specified endpoints, which is its core technical function.
