Global ICMP Ping & Network Latency Test
我們的 Ping 檢查工具會從全球多個地理位置,發送 ICMP (網際網路控制訊息協定) Echo Request 封包到指定的 IP 位址或主機名稱。這能幫助您確認伺服器是否可達、測量網路延遲,以及偵測跨國連線路由中的封包遺失狀況。
Latency and Packet Loss
透過全球不同的節點進行 Ping 測試,您可以判斷連線問題是侷限於特定地區,或是目標伺服器的基礎設施已經完全無法連線。請注意,某些具有嚴格安全性設定的防火牆或雲端負載平衡器會刻意阻擋 ICMP 封包:在這種情況下,使用 HTTP 或 TCP 測試可能會提供更準確的可用性狀態。
Anycast & BGP Routing
Modern Content Delivery Networks (CDNs) like Cloudflare, Fastly, and AWS utilize Anycast routing, where the exact same IP address is announced globally. A distributed ping test reveals if traffic is being correctly routed to the closest geographic edge datacenter, or if BGP misconfigurations are causing improper international routing.
Live Monitoring Mode
Standard ping tests send a finite burst of packets to generate a static snapshot. By utilizing the Live Ping feature, engineers can establish a continuous 60-second ICMP stream. This real-time charting is crucial for diagnosing intermittent connection drops, tracking jitter, and observing volatile network stability during active DDoS mitigation or incident response.
