Enter a domain to receive real-time DNS, HTTP, Ping, Traceroute, SSL, ICP, and WHOIS diagnostic results via SSE

• Real-time push：Diagnostic progress is streamed in real time via Server-Sent Events (SSE)
• DNS Resolution：Checks the A record resolution result for the domain
• HTTP Reachability：Tests HTTPS accessibility and response time
• Ping Latency：Measures network latency and packet loss
• Traceroute：Traces the route path to the target server
• SSL Certificate：Checks HTTPS certificate validity and expiry
• ICP Filing：Queries MIIT ICP filing information
• WHOIS：Queries domain registration info and expiry date
One-click diagnostics takes a single domain and automatically runs DNS resolution, HTTP availability, ping latency, traceroute, SSL certificate, ICP filing, and WHOIS checks in sequence, streaming each result in real time. Instead of running every tool by hand, you get a complete health picture of the domain in one go.
It is ideal for quickly locating a problem when a site misbehaves: whether it's a resolution failure, link latency, an expired certificate, or a reachability issue. It collapses scattered diagnostic steps into a single action so you can narrow down the cause fast.
The results are the same, but one-click diagnostics runs all seven checks in sequence and summarizes them, saving you the manual work — better suited to quickly pinpointing which part of a site is broken.
Most checks finish within seconds; traceroute and SSL validation can take a little longer. Progress streams in real time, so you see completed checks without waiting for everything to finish.
No. Each check is independent — a single failure (e.g. no ICP filing, a certificate issue) is flagged on its own while the rest return as usual.
Drill into the failing step: check DNS for resolution problems, multi-location ping and traceroute for link latency, and the HTTP check for availability issues.
