Uptime Monitoring

Enterno.io checks your website every minute from multiple locations worldwide and alerts you instantly when it goes down. Know about outages before your users do. Start monitoring for free — no credit card required.

How Uptime Monitoring Works

Our servers send HTTP requests to your website at a set interval — as often as every 1 minute. When a 4xx/5xx response code or timeout is detected, an incident is recorded.

  • Checks every minute (Pro plan)
  • Multiple geographic locations to prevent false positives
  • Response time tracking (ms)
  • Incident history with downtime duration

What Gets Checked

Uptime monitoring covers:

  • HTTP/HTTPS status code (200, 301, 302...)
  • Server response time
  • Keyword presence on the page
  • SSL certificate expiration
  • IPv4 and IPv6 reachability

Why Uptime Matters

Every minute of downtime costs revenue. Search engines factor uptime into rankings. Users abandon slow or unavailable sites in under 3 seconds.

Enterno.io stores incident history and generates SLA reports — useful for your team and clients.
