undernet/#db not showing on MIRC?

I've been trying to get on the IRC via web applet aswell - and it freezes up Chrome.
Downloaded mIRC and undernet isn't listed as a server.

Try connecting to eu.undernet.org. They're having issues due to a larger ddos effort that servers were caught in the middle of. Other IRC networks are also experiencing issues. There are only 3 servers accepting connections as of 1 hour ago.
