Is your host reachable right now - and how fast does it respond from outside your network.

Network reachability and latency in plain terms
When a server stops responding, users see timeouts and APIs fail - often minutes before your internal monitoring catches it from inside the same network.
A ping test checks reachability and measures response time from external servers. We use TCP connect probes when ICMP is blocked - the same practical answer as "is this host up?"
Run a free ping test during incidents or after deploys. Add hosts to TotalSiteControl uptime monitoring for automatic checks and alerts when response times spike or connections fail.
Start free monitoring with email alerts. No credit card required.
Check whether a host answers from the internet in under a minute - no account needed.
Type a domain or IP, for example yourdomain.com or a public server address you are allowed to test.
Click the ping button. We probe reachability from our network and report whether the target responds within the timeout.
See if the host is reachable and how latency looks from our probe. Use that signal to debug outages, then add monitoring for ongoing uptime checks.
What “no reply” often means - and what to check next.
The probe times out. The server may be down, firewalled, or blocking ICMP/TCP probes from outside.
Check the process and health endpoint on the server, open the expected port for public checks, and re-test the same hostname visitors use.
Some probes succeed and others fail. That often points to overload, flaky routing, or rate limits.
Review CPU, connections, and upstream network. Re-run ping during the incident window, then turn on monitoring to catch repeats.
DNS looks fine while the app or origin does not answer. Ping alone may not show an application error.
Verify the IP with ping, then check HTTP status and headers for the public URL so you see both network and app health.
Certificate, DNS, and reachability history in one place.
Checks run from our servers - the same path users hit.
Turn a one-off check into monitoring in under a minute.
External probes so internal network blind spots do not hide issues.
Email and Telegram when something fails or is about to expire.
Start free - no credit card required to begin monitoring.
Start free monitoring with email alerts. No credit card required.
Use ping as a first signal, not the only one.
CDN and load balancer frontends can differ from the origin IP. Test the public name first.
A timeout is not always an outage. Confirm whether the provider filters external probes.
One timeout can be noise. Re-run after a minute before you escalate.
One-off pings miss overnight failures. Scheduled checks with alerts catch drops while you sleep.
Whether a host is reachable and how long TCP connections take from our servers - the same path a browser or API client would use.
Yes. Test any public hostname or IP instantly - no signup, no credit card, and no limit on one-off checks.
We use TCP connect probes when ICMP is blocked on the target. You still get a clear reachable or unreachable result plus response times.
You may be testing a blocked port, the wrong hostname, or a network that filters probes from outside. Try the exact hostname users visit.
Under 100 ms is typical for nearby hosts. Above 300 ms may indicate routing distance or network congestion.
Yes - enter any public IP such as 8.8.8.8 or a hostname such as yoursite.com.
Common causes include firewall rules, the service being down, wrong DNS, or the host being offline. Pair with our DNS Lookup to confirm the name resolves.
During incidents and after infrastructure changes. Uptime monitoring runs checks automatically and alerts on failure.
