How to use it
- Enter a host (domain or public IP).
- Choose a port for the service you expect (common: 443 for HTTPS).
- Click Ping to run multiple attempts.
What this measures
- TCP connect latency (not ICMP echo).
- A timeout can mean a firewall is filtering traffic, or the host is unreachable.
- Results depend on where this server runs (not “from your computer”).
