mac problem

What do yo men by this site?

Can't be reached from what device? What OS and version? What app/browser?

What happens when you try? What exactly appear on the screen?

Maybe:

If Safari is slow, stops responding, quits unexpectedly, or has other issues - Apple Support

If Safari doesn't load a page or webpage items are missing - Apple Support

If you are referring to Apple Support Communities, the Apple moderators occasionally take the site down for maintenance usually for just a short time.

You may see this occasion..
