How do we check if sem40.ru is down?
1) We check the sem40.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 sem40.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 sem40.ru is up or down. Coming soon - We are working on a new feature that will enable you to report problems and errors with sem40.ru directly from this website. You will also be able to view what other sem40.ru users are reporting and see past issues and outages.
