The web page 

has several links to URLs of the form 

that is, links containing the "domain name" 

to the right of the double slash.

I noticed today (this am, and then again this afternoon) that there 

was some difficulty dereferencing those links (going to those URLs) . 

(I tried this using both Firefox [3.6.3] [w/ Mozilla/5.0 & Gecko/20100401] 

Both browsers -- (Firefox and Chrome) -- were unable to find 

the server "lists.plug.phoenix.az.us". 

Is this something temporary?  and/or, it is something that the 

PLUG server maintainer persons "know about", but which takes a 

while (a long time) to fix?  (for the issue to be addressed?) 

OR (aha) is it me?  (is no one else seeing the same problem?) 

OR is http://plug.phoenix.az.us/email_lists somehow deprecated 

(in which case I 'should have known' to use some alternate for it, 

and not to use it, and not even to TRY to use ["CLICK on"] the 

links that it contains?) 

TIA,
