You can use Looking Glass-servers to check if the IP address of your server is available. You can find out the IP address of your server in Servers menu.
For example, on www.traceroute.org select the country from which you want to check the availability of the server. Let it be Russia. After that choose one of the servers, for example lg.telia.ru. An example of checking the availability of our server fornex.com is given below:

Similarly, you can check the availability of your server. If you notice any availability problems, please write to our support and specify from which server and for which IP address you have checked availability. We will analyze and solve the problem immediately.
If the server is accessible from any Looking Glass server, but you still can not connect to it from your computer, you need to check the availability of your computer. First of all, determine your external IP address. This can be done by following these links:
Once you know your address, you can check its availability, and if you notice problems, contact your ISP's support and provide them with the results of the check.
