The Free Software Foundation (FSF) Web Site is Online, GNU's Site Having Issues (Ongoing Issues)
The site of GNU is down at the moment. It seems like a persistent issue, verified both here, on the server side, and third parties:

It seems like many other people checked the site's availability as well.
In the FSF, a sysadmin became an administrator (or head) of the Board, a Web developer became a sysadmin, and the FSF's site is still reachable.

We hope they can rectify the issues with the GNU Web site. We don't know the root cause, we've asked around, and we'll update this article if we belatedly hear something. █
