Can't resolve hostname on minecraft survival game server?

The server I go to goes through periods where it works and then through random periods where it doesn't work. It says "can't resolve hostname" but I have been on this server plenty before so I know the IP address isn't wrong. It is a minecraft survival game server. It's really annoying because I have Wi-Fi connection and bought the game. Help?
