Could it be your firewall blocking it? Some pop up blockers can mess with sites loading too.
Edit: the REOS site has the age confirmation pop up when it loads. Something in your security settings may not be allowing that form to come up.
Thanks LA. I'll check the firewall settings and the popup blocker again - maybe the settings got changed when I upgraded to Maverick. I think that's about the time I started to have problems accessing the site.
The error message I get say, XXX (browser name) cannot find the server.
