How do we check if bd72.ru is down?
1) We check the bd72.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 bd72.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 bd72.ru is up or down.
