Global TCP Port Checker & Network Connectivity Test
TCP 端口检查器是一个诊断工具，用于确定网络设备（如服务器或路由器）上的特定通信端口是否打开并能够接收流量。
Firewall & Routing Validation
虽然 HTTP 监控在应用层运行以验证网站内容和响应代码，但 TCP 端口检查器在传输层工作，严格关注建立连接的能力。
Application vs. Transport Layer
该工具也可以与超过 60 秒的实时数据一起使用。为此，请使用重复按钮。
Handshake Latency Analysis
The time measured in a TCP check is specifically the round-trip time required to complete the TCP handshake. Tracking this latency globally helps identify suboptimal BGP routing or unoptimized Anycast networks. Our Live TCP mode allows for real-time monitoring of this latency to catch intermittent connection drops.
