HTTP Probe
reachability + latency from this server
DNS, TCP, TLS, and HTTP timing to your domain — measured from this site's server, not your browser. Not ICMP; works on Vercel.
How it works
Resolves the host, connects to the public IP on 443 (HTTP fallback on 80), times each phase, follows up to 3 redirects with re-validation, and runs 3 samples for min/avg/max/jitter. The tools page also pulls a first-paint screenshot (≤10s). Private and localhost targets are blocked.
