So I'm having an ongoing issue with my University's grade portal website. However, the problem only exists on my laptop (2011 MBA). Basically, the website just doesn't load at all anymore (on this computer). It worked for a long time, and I noticed about three weeks ago it was no longer loading. I simply get the "xxx.edu can't be opened because the server where this page is located isn't responding." I really need this website to be working for me on this computer, and I really can't figure out why it'd just randomly stop working. Here's a few things: 1. I've restarted my computer. 2. I've completely reset Safari (cleared all cache, cookies, everything- all boxes were checked on the Safari restart). 3. The website loads (not very well however, many features don't work) on this computer (my MBA) via any proxy server. 4. I've reinstalled Safari. 5. I've tried other browsers (Chrome, Firefox) and no luck. So what's up? I could really appreciate some advice here. Thanks.
