I can't connect to many apple developer pages (App Store Connect) from my Mac but I can connect from a Win7 machine and iPad. Connections to the server are not being made or I just get a spinner. I can connect to apple.com and other pages from the MAC using Safari but not this site which seems to be used for all apple developer pages including the forums. I've tried clearing the history in Safari but that didn't help.
