Check website availability from 30 checkpoints

Your website might not load for you, but there is always a chance it is because of your internet service provider, browser, or other local problems. Also, your website might be unavailable only in the region you live in. Use our website availability tool to get detailed information about your website's health from around 30 checkpoints on 6 continents.

Check page loading time from around the world

In addition to the website availability check, it also shows how fast your site loads in each location. You can use this information to find out if your website is fast on all continents. We use a real Google Chrome browser to load your website entirely, with all heavy design elements.

How does this tool work?

We send a command to load your website to around 30 website monitoring probes and wait for an answer. As soon as we get a response, we display the loading times on the map to get a clear view of your site responsiveness worldwide. Also, we provide more detailed information in the table below. Just enter your website URL, and we will check its availability immediately.

How to use our website availability checker tool?
