HTTP(S) monitoring is the most common and most important check for any website. Uppinger sends a request to your URL on a schedule and verifies that it responds with a healthy status code (200 OK) within an acceptable time. The moment your site returns a 5xx error, a timeout, or stops responding entirely, you get an alert.
Checks run from multiple geographic locations, so a single network blip never triggers a false alarm — a downtime is only confirmed when more than one location agrees your site is unreachable.
How HTTP(S) Monitoring works
Add your URL
Enter any HTTP or HTTPS endpoint — a homepage, a login page, or a JSON API.
We check on schedule
Uppinger requests your URL as often as every 30 seconds and records the status code and response time.
Confirm from multiple locations
Before alerting, we re-check from a second location to rule out false positives.
Get instant alerts
When downtime is confirmed, you are notified by email, SMS, Slack or Telegram within seconds.

Frequently asked questions
What is HTTP monitoring?
HTTP monitoring is the practice of regularly sending an HTTP or HTTPS request to a website or API and verifying it responds correctly and quickly. It is the fastest way to detect downtime.
How often does Uppinger check my site?
Depending on your plan, checks run as frequently as every 30 seconds. Free accounts check at a slightly longer interval.
Will I get false downtime alerts?
No. Before sending an alert, Uppinger re-checks your site from a second location, so a temporary network glitch on one node never triggers a false alarm.
