Unable to access site?

[John]

1. For your domain to work, please allow 24-48 hours for the DNS to update. For some users, they should be able to see their subdomain right away.
2. Also, if you are using your own domain, please update the nameserver for your domain to the ones that we have provided to you in email. After you update the dns, please allow 24-48 hours for your domain to start working.
3. check your firewall settings because some software might block the site. http://service1.symantec.com/SUPPORT/nip.nsf/docid/2004093010421136?Open&src=&docid=2001121211273436& nsf=nip.nsf&view=docid&dtype=&prod=&ver=&osv=&osv_ lvl==
