www.flyertalk.com which for me resolves to web1.flyertalk.com as basicly been non-operative for me all day, only intermitantly at best does it work. If I use web2.flyertalk.com then it works for me.
If those are seperate machines then web1 seems to be sick, if they are the different names for the same machine then your DNS entry seems to have a problem.
(Feel free to PM me with technical questions if you have any that will be of help)
