Looks like their website is also down.

I typed this in my status window:

Code
/dns irc.othernet.org


And I got this:

Code
[11:57:48] * Dns resolved irc.othernet.org to 23.237.154.234, 23.237.10.138


I tried connecting with:

Code
/server 23.237.154.234


That got me connected to Chicago.IL.US.Othernet.org.
