What error is returned from those who cannot connect?  

Is everyone using the same URL?  Are you positive?

Are the problem users inside or outside your network?

Is there a non-SSL portion of your web site the problem users can access?

Who issued your SSL certificate?  Have you updated it to 2048-bit?

There is no portion of website that is non-SSL

Do the West Coast clients connect to the same server as those on your ISP?

Do the West Coast clients not resolve the URL?  Or do they get an indication that the SSL certificate is bad?  Some other sort of error?

FWIW, I remoted into a machine in Hawaii and was able to access the SSL site.

this seems to be compatibility issue I just booted the old web server and clients are able to access is there a way to make IIS 8 backward compatible?

The server won't be the problem.

Is is possible the newer server/site was configured to block traffic from certain IPs?  As I noted, I can get in from either coast.  

I don't know how wide-spread your problem is, or how aggregated the problem users are, so it's difficult for me to be constructive.  Also, you've still not indicated what error these users receive, which might go a long way toward identifying the issue.

Can these clients ping the web server?  That is, can they resolve the IP address from the host name?  It's not impossible this is a DNS issue.  Do they get a different error if they try to connect to https://50.240.97.74/ ?

Are all your clients running older browsers?  If they're old enough, they may not accept the newer certificate.   (this is not a likely scenario, but...)

I don't know what "they are running IE 8 on windows xp proxy server" means.  Are they in a terminal server environment?

You noted that when the old web server was brought online these clients could connect to it.  Does it use the same public IP address as the new web server?
