How do we check if epub.press is down?
1) We check the epub.press server to see if it is responding and we do this from a region
closest to you. This test we perform simulates what an actual web browser (e.g. Safari, Chrome,
Firefox) would do when trying to visit the website.
2) We determine if the epub.press server is returning an error message that indicates some
sort of problem. These types of errors generally mean that a visitor -- you -- would also have
trouble using or visiting the service.
3) We return the results of our test from our servers and let you know if epub.press is up or down.
