The correct address is plug-security@lists.plug.phoenix.az.us.  Lisa just got the address wrong the first time by forgetting the ".plug." in the middle.  No fault of Deru, or DNS or the server or administration.  Just a typo.

It happens.

Please don't post wild conclusions, the plug-security list has existed for more than a decade and has almost 300 people signed up for it. There is no way we would remove it.  You simply fell victim to a DNS outage.

Hopefully we will be moving the DNS to our own servers soon, as the service we have been getting from DERU, where our servers are co-located, has been top notch, and we have never had any problems with it at all.  Once we have the DNS hosted with them, I expect to never have any unexpected down time again.

Unfortunately,

Someone has removed the mailing list after we announced we were using it.
They gave us no notice it was gone.

It was PLUG-Security and there were more than a few people signed up to
use it.

It has been removed now?  Not sure why.  Perhaps we need to move to a
better hosting solution?  I have more than enough disk space on my
GoDaddy virtual host?
