When you are unable to get to SOG with the URL of
http://www.portraitartist.com, have you then tried
http://199.217.241.56 as I've suggested earlier? It should come up, which would be proof that the problem is with their name servers and caching procedures. If you have not done this, please do so and tell me what happens. But, the fact is, in conversations between my host company and AOL, AOL has admitted it is their problem.
When you have the problem, see if you also have the problem with the following sites. Please report the results.

http://www.leonloard.com
http://www.st-louis.net
http://www.autotire.com
http://www.newground.com

I signed up for the free month with AOL and unfortunately encountered the problem only one time and was unsuccessful in getting help from tech support because I kept being disconnected during each online support session and when I got disgusted and finally signed off and then back on, the problem was no longer there.
