We monitor your website availability from multiple locations worldwide

Our uptime checks run every minute from a location of your choice. Once we have confirmation that your site is down, we'll notify you instantly.

We'll alert you if your site goes down

There are many reasons a site can go down.

HTTP/1.1 500 Internal Server Error
Server: nginx
Date: Tue, 21 Sep 2021 07:35:35 GMT
Content-Type: text/html
Content-Length: 531
Connection: keep-alive

Whatever the cause may be, we alert you instantly. With all the details to help you troubleshoot the problem & fix it.

Via email, SMS, Slack, Discord, ... you name it. We've got plenty of notification options.

Here's how that might look.

The technical explanation of what we monitor

We monitor what truly matters: your application or website.

If we fail to receive an HTTP/200 response within a reasonable timeframe, we mark your site as down. When we see website failures for 2 minutes in a row, we send out notifications so you can intervene. This prevents monitoring flaps and false positives.

You can change the timing threshold in your settings. Prefer to get alerted after 5 minutes instead of 2? Not a problem.

Our downtime reports give you all the details to quickly verify and troubleshoot any alert.

In our report you'll find useful commands to replicate our monitoring, this allows to you see exactly what we see.

Content verification & checkstring monitoring

Is just monitoring a status code not enough? We can verify the existence of a piece of text on the page too (a so called "checkstring"). If we receive an HTTP/200, but the checkstring is missing in the source code, we'll mark the site as down.

Monitoring beyond a GET request

By default we monitor using a GET HTTP call, but you can also change this to POST, PUT or PATCH.

Each method can have its own form payload. This allows you to simulate a form submission and monitor search results, contact forms, API endpoints, ...

You could even perform a website login through a POST call and verify the account page loads properly.
