Bob - For giggles I ran the PAMPA ip you listed on
http://www.blacklistmaster.com/check to see if we have been blacklisted. According to them, yup, our server is blacklisted at three services. AT&T probably subscribes to one of them, hence blocking us.
This was the report result:
Listings of 216.10.246.91
b.barracudacentral.org - Barracuda Reputation Block List
dnsbl.sorbs.net - SORBS Aggregate zone
IP.v4BL.org v4BL.org - (D. D. N. S. B. L.)
You will have to fill out forms and petition these services to take us off their lists. Someone probably was using the server that hosts PAMPA as a jump point to blast out some spam or DOS attack...

All;
The PAMPA web site is up and running, but there is a lot of finger pointing going on between Internet Service Providers as to why it is being blocked. If you can not get to the site, I strongly urge you to contact the tech support for your ISP and ask why access to domain control-line.org associated with IP address 216.10.246.91 is being blocked and what they are doing to fix it.
In the interim, for those who wanted to get the Sep-Oct 2012 "Stunt News", I have it loaded on another server in the Atlanta, GA area, for direct download. Please contact me via email and I will send you the link.
My apologies for the inconvenience.
