Reddit has removed the front page of the Internet, replacing it with algo personalized feeds. From the change log:

"Entry points and links to r/all being removed starting today What’s changing? As part of ongoing efforts to simplify Reddit and improve Home feed personalization, the final steps to deprecate r/all are being implemented. All links to r/all will now redirect to the Home feed, following the prior removal of r/all entry points. Trending content remains available via r/popular.

Redditors on old.reddit.com, or those with settings that default to the old Reddit experience, will continue to access r/all as expected."
