Can't view our site(or other Chicago sites)

We're having an issue and I'm 99.9% sure it has something to do with Chicago servers. I've pulled up TN sites that use NY servers and they work fine. I can't view any of these:

http://thebrunswicknews.com (our site & the backend)

http://help.bloxcms.com/

http://docs.townnews.com/kbpublisher/

http://www.onidawatchman.com/

http://www.lodinews.com/

http://www.gulfcoastnewstoday.com/

http://www.idahopress.com/

I'm not sure because I can't see which servers they're on but I'd be willing to bet they're all Chicago. This issue isn't limited to us. We've got someone traveling in North Carolina and he can't access our site either.

So I guess this question is: Is anyone else on a Chicago server unable to access any other Chicago servers?
