Help-Internet Problem

My internet is being strange :rolleyes:

I thought it wasn't working at all because the page would not come up, I called the cable tech support and they told me to try a different site, and it worked fine.

So it's not working on the only site I need it to work on, why would some sites not work?

Thanks

That site is just down, more then likely, under repair of something, give it time.
