How do we check if zdr.ru is down?
1) We check the zdr.ru 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 zdr.ru 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 zdr.ru is up or down. Coming soon - We are working on a new feature that will enable you to report problems and errors with zdr.ru directly from this website. You will also be able to view what other zdr.ru users are reporting and see past issues and outages.
