The Where's It Up? API provides a broad suite of tools to make sure your websites are available, speedy, and properly localized.

DNS Testing

Our DNS monitoring provides global domain insight, performing tests from around the world to ensure accurate DNS records. Diagnose TTL problems or confirm the details for that new IPv6 address.


Availability tests let you ascertain service availability and accessibility using our global network. Verify that your users in South Africa can access your content, just like users closer to home.


Speed tests provide concrete metrics for page load time and large file delivery speeds from our global edge endpoints. Performance is key, and the speed tests let you make informed changes to tune your site.


Routing problems can be devastating and difficult to diagnose. Our network helps you probe (and understand) your own from a global perspective.


Generate screenshots to allow your team to see what your global customers are seeing, and monitor their results constantly.
