Where's it up? provides a network of servers that allows users to make sure that their websites are up wherever a server is located. Locations include cities around the world with a focus on North America and Eurasia. Each server is capable of local DNS resolution. Where's it up? can follow a reasonable number of redirects and will report back IP and timing information. Users can access Where's it up? programmatically by issuing JSON-formatted POST calls to the server.
