Two new servers added today, Tunnel15 and Aussie2.
If you're using the new client, you should receive the server list update automatically.
If you're using Putty to connect, you can download an updated list here:

Just like to remind also, that Aussie2 should be used only if you're having lag spikes, disconnections in raids/heavy encounters. If you have no problems using the standard servers, continue using them as you'll get better performance.
Also like to note that in the future, Aussie1 and 2 will have a hard cap of 140 players at once.
