Actually this site loads very slow for me when I am at work. In my case it is not my internet connection or PAFOA's internet connection it's the COGENT network being really really slow in between.
I'm not sure if that's the case on your end though.
If you are comfortable using the command line on your computer open it up and type:
tracert
www.pafoa.org
And paste the results back here. If you have no idea what I am talking about then just ignore me.
Not sure what else I can do to help you on that one though.
