Get Started
No credit card required.
UptimeObserver pings your servers from multiple global locations every 30 seconds. Get alerted the moment packet loss exceeds your threshold, latency spikes, or your server stops responding entirely.
🚨 db.example.com unreachable. 100% packet loss — last response 548ms ago.
Why It Matters
Even a few dropped packets can cripple real-time applications. We ping your servers continuously and alert you the moment packet loss exceeds your defined threshold.
Track round-trip time and jitter in milliseconds. Get alerted when latency exceeds normal baselines—catch network congestion, routing issues, and ISP problems before they cause outages.
Ping your infrastructure from multiple continents. Know instantly whether a connectivity issue is isolated to a single region or affecting your entire global user base.
Quick Setup
No agents to install. No code to modify. Just add your host and let us ping it.
Enter the IP address or hostname you want to monitor. It can be a web server, database node, VPN endpoint, or any device that responds to ICMP ping.
Define acceptable packet loss and maximum latency. We alert you the moment your thresholds are breached—whether it's 1% loss or 200ms of added latency.
If your host becomes unreachable, packet loss spikes, or latency exceeds your defined ceiling, we alert you immediately on your preferred channel—Slack, Discord, SMS, email, and more.

When you monitor your servers with UptimeObserver pings, you unlock an entire suite of enterprise-grade infrastructure monitoring.
