EDIT: Nevermind, it seems to just take longer than normal. After refreshing 5 or 6 times servers started to appear.
When I try to find a server, it searches for a minute or so and then gives me the message "No internet games responded to the query." This makes it exceedingly difficult to playt TF2. If my friends are in a game, or if I have a specific server's address I can join like normal. The spectate list all works normally, showing me a long list of servers.
