Well, basically, nothing from the USCIS domain will load for me. It'll stop at 2.6 Kb (That's if I'm lucky!) and after 25 seconds my internet browser will tell me that no such domain exists. I've tried three different browsers (IE, FireFox, and Opera) and even turned off my firewall. Still, I get the same response from the internet. Unfortunately, I don't have easy access to another internet connection, except at work...but they have the almighty, alcrappy INTRANET that only allows internet access to the company's sites and services. I've never run into a problem like this before in all my years of tinkering with computers.
And rea, I tried that site that you linked me. The first page loaded up okay. Everything I clicked on did the exact same thing that the main USCIS website would do. It either failed to load or stopped at 2.6 Kb.
