I have a recent problem with trying to browse a couple of my regular websites. When I try to view them I get "Firefox can't establish a connection to the server at" messages, instantly with no even trying to access the domains. I tried ping and tracert commands in the command prompt, and both failed to connect to the domains. However, when I go to any proxy/unblocking website and enter these sites, they will load fine through proxy so I know they're online. They were showing up as "down for everyone" a few days ago, checking via websites that check domains, but they're working now.
