No connection

I can no longer connect to this site despite white listing the urls and despite have no pop-up blocker and a fast internet connection. Any other suggestions?

I would just wait a bit, My school uses this programming website and sometimes they just get overwhelmed and freeze up. I know for us sometimes we just have to wait a few days, sorry for the inconvenience though. :confused:

thanks for that. I have noticed that it connects once in awhile.
