I can't access their site either.  If I use IE it say page not found.  If I use Chrome it says 

No data receivedUnable to load the webpage because the server sent no data.

Here are some suggestions: - Reload this webpage later.

Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.

 

And Firefox says:  The connection was reset

The connection to the server was reset while the page was loading.

The site could be temporarily unavailable or too busy. Try again in a few

moments.
If you are unable to load any pages, check your computer's network
connection.
If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.

 

I just tried the link that WandW offered and got the same message as above.

This just started last week or the week before, can't remember now.  I was getting there fine before that.
