One specific website won't load
While browsing the internet on my laptop (late 2011 MacBook Pro, 2.4 GHz Intel Core i5 processor), I have one specific website that will not load. It's worked in the past, but has suddenly stopped working.
My software and OS are up-to-date (OS X 10.9.5), and I've scanned for viruses (Intego VirusBarrier). I've tried multiple networks (WiFi only, no ethernet), haven't changed my network or firewall settings, and have tried disabling my firewall (Intego NetBarrier). I've tried multiple browsers (Safari, Firefox, and Chrome), reset Safari to clear my cookies and cache, and have disabled the one browser extension I use.
I've been able to access the site on other computers and on my iPhone, all on my primary network. I've opened the terminal and used the host command, and I know my computer is able to interpret the site's IP (something about verifying the DSN?). As best I can tell, this is not an issue with the website, but with my laptop.
Any ideas?
MacBook Pro, OS X Mavericks (10.9.5)
