Question about non working site in FC2, Mozilla

["Bradley \(FC2 List\)" <FedoraList Thingbuilder com>]

I forwarded a URL to my wife to check out:
http://www.linuxchix.org/

I can open this URL on a Windows machine with either Thunderbird, IE, or
Mozilla.
I can't open it on my FC2 machine and my Wife can't open it on her FC2
machine, both using
Mozilla.

Is it just me?
If so, where should I look for a solution?

Thanks,
b
