Well, For whatever is worth and for the nice guys who responded with suggestions about this matter. Today, for some magical reason, the website works again. The 404 error is gone! I never did anything about it, it just happened. oscar -----Original Message----- From: Oscar Castaneda [mailto:[log in to unmask]] Sent: Thursday, March 13, 2014 11:56 AM To:[log in to unmask] Subject: [MSUNAG] an IP blocked? I tried to go to a website off campus. I got an "HTTP Error 404. The requested resource is not found." I just assumed that the site was down. To my surprised a lot of people off campus told me that it was up and working. It turns out that it does not work only on Campus. I was wondering if this is server that is blocked from Campus. If so, why do I get a 404? How can I find if it is indeed blocked? Is there a list of blocked IPs/domains? -- Oscar Castaņeda Remote Sensing & GIS Michigan State University
