Is Xtrek and/or Netrek Dead?

The post at http://209.120.143.185/showthread.php?threadid=178350
reminded me of Xtrek/Netrek. So I tried to check it out and pick up a current client. Although http://www.inl.org/netrek/netrekFAQ.html and http://www.netrek.org/
exist, the links are dead.

Is Xtrek and/or Netrek Dead? I just played an arkanoid applet the other day, you'd think Xtrek and/or Netrek would also survive or be remade.

If it's alive, where can I get a client? Maybe even server source and I could setup my own. Please post active links.
