Host Check API
Check whether a host or website is reachable from dozens of locations around the world as an API, powered by check-host.net. Run an ICMP ping, an HTTP request, a TCP-port connect or a DNS resolution from many countries at once and get a per-node breakdown — reachable or not, response time, resolved IP, HTTP status code or DNS records — plus an aggregate "reachable from X of N nodes". Perfect for answering "is it down for everyone, or just me?", monitoring global uptime and latency, verifying CDN and geo-routing, debugging firewalls and regional blocks, and powering status pages. Also lists every available worldwide check node. No accounts, no agents to install.
