Monitoring Tools Built for Reliability
Multi-Location Checks
Monitor from data centers across North America, Europe, and Asia. Detect regional outages and routing issues that single-location tools miss.
1-Minute Check Intervals

Phone Call Alerts
Wake up your on-call team with actual phone calls. SMS and email can wait; critical incidents need immediate attention.
SSL Certificate Monitoring
Get alerts before your SSL certificates expire. Avoid browser security warnings that destroy user trust and conversions.
Response Time Tracking
Monitor performance degradation over time. Get alerted when response times exceed your defined thresholds.
Public Status Pages
