What is Uptime Monitoring?

Uptime monitoring is the practice of continuously checking whether a website, API, or online service is accessible and responding correctly. It measures availability over time and immediately alerts you when downtime occurs, so you can respond before users are affected.

A reliable website uptime monitoring tool sends HTTP requests to your endpoints at regular intervals and verifies that the response matches expected criteria such as status codes, response time thresholds, and content checks.

Why Website Uptime Monitoring Matters

Downtime directly impacts your business:

• Revenue loss — every minute of downtime costs money, especially for e-commerce and SaaS businesses
• SEO impact — search engines penalize sites with frequent or prolonged outages
• User trust — visitors who encounter errors are unlikely to return
• SLA violations — missed uptime targets can trigger contractual penalties
• Brand reputation — repeated outages erode confidence in your service

Uptime monitoring ensures you are the first to know when something goes wrong, not your customers.

How Uptime Monitoring Works

Our free uptime monitoring tool works in four steps:

1. You add your website URL or API endpoint
2. Our probes send HTTP/HTTPS requests at your chosen interval (as low as every 1 minute)
3. Each check verifies the response status code, response time, and SSL certificate validity
4. If a check fails, you receive an instant alert via email, Slack, or webhook

All checks are recorded with full response time history, so you can track performance trends and identify patterns over time.

Multi-Location Monitoring

False positives are one of the biggest problems with basic uptime monitoring. A single-location check can report downtime due to a local network issue rather than an actual outage.

Our multi-location uptime monitoring solves this by checking your website from 7 independent probe locations across the globe:

• Amsterdam (Netherlands)
• London (United Kingdom)
• Frankfurt (Germany)
• Warsaw (Poland)
• US East (South Carolina, USA)
• India (Delhi)
• Australia (Sydney)

With multi-location monitoring, incidents are confirmed by multiple probes before alerting, virtually eliminating false alarms. It also helps you detect regional outages that only affect users in certain geographies — something single-location monitoring cannot do.

WordPress & CMS Websites

Ensure your WordPress site stays online after plugin updates, hosting changes, or traffic spikes. Combine with SSL monitoring to cover all critical aspects.

API Monitoring

Monitor REST APIs with custom HTTP methods, expected status codes, and response time thresholds. Verify that your API responses meet SLA requirements from multiple geographic locations.

Frequently Asked Questions (FAQ)

What is uptime monitoring?

Uptime monitoring is the process of continuously checking whether a website or service is online and responding correctly. It tracks availability over time and alerts you when downtime is detected.

How does multi-location monitoring work?

Multi-location monitoring checks your website from multiple geographic regions simultaneously. Our probes in Amsterdam, London, Frankfurt, Warsaw, US East, India, and Australia all verify your site independently. An incident is only confirmed when a majority of locations report failure, which eliminates false positives caused by local network issues.

What check intervals are available?

Check intervals range from 1 minute to 30 minutes. The default is 5 minutes, but you can configure 1-minute intervals for critical services that require the fastest possible downtime detection.

Is the uptime monitoring tool free?

Yes. Our uptime monitoring is completely free with all features included — multi-location checks, SSL monitoring, alerts, and response time tracking. No credit card is required.

How do I get notified when my site goes down?

You can receive alerts via email, Slack, or webhooks. Notifications are sent immediately when an incident is detected and again when your site recovers.

What is a good uptime percentage?

Industry standard is 99.9% uptime (often called "three nines"), which allows for about 8.7 hours of downtime per year. Critical services often target 99.99% (52 minutes/year) or higher. Our monitoring helps you track and maintain these targets.

Can I monitor APIs and not just websites?

Yes. You can monitor any HTTP/HTTPS endpoint including REST APIs, GraphQL endpoints, health check URLs, and webhook receivers. You can configure custom HTTP methods (GET, POST, HEAD) and expected status codes.

What regions do you monitor from?

We monitor from 7 locations: Amsterdam (Netherlands), London (UK), Frankfurt (Germany), Warsaw (Poland), US East (South Carolina), India (Delhi), and Australia (Sydney). You can select which locations to use for each monitor.

How does uptime monitoring differ from ping monitoring?

Ping monitoring only checks if a server is reachable at the network level. Uptime monitoring performs full HTTP/HTTPS requests, verifying status codes, response times, SSL certificates, and content — giving you a complete picture of whether your service is actually working for users.

Can I combine uptime monitoring with SSL and DNS monitoring?

Yes. Our platform offers integrated SSL certificate monitoring, DNS monitoring, and uptime monitoring in a single dashboard. This gives you full visibility into your website's availability, security, and DNS health.
