Unable to open web site

I'm not sure the best place to enter this question but for the past week I've found that one site in particular, www.hotornot.com (don't laugh) won't open. Both Firefox and Internet Explorer just sit in a "connecting" status and then time out. I've tried disabling my firewall (Symantec Endpoint Protection), resetting my cable modem, deleting Internet cache and history, etc. and nothing works. Friends of mine say they have no problems accessing the site so it is something on my end. All other websites seem to be working at the moment. Any thoughts on troubleshooting? Could it be a network card setting? I have a Realtek 8168/8111b adapter with a ton of settings under properties that I have no clue about. Please advise. Thanks in advance.
