Posts on a FB page are not shown to page followers. Glitch or ban?

Question

Facebook

Good afternoon
There is a page for 40k subscribers. It published 5 posts per day with a link to the site and 1 note and 1 photo. The page received good coverage and engagement.
2 days ago, posts with a link to the site stopped receiving coverage, subscribers do not see them in their news feeds. Statistics for such posts show zeros (zero reach and zero engagement). In this case, the note and the photo diverge as before.
Tell me the answer to this riddle, is it a FB glitch or some kind of ban?
Addition:
1. I tried to publish a post with a link to another site for the test - coverage is zero.
2. Added another editor and tried it with aka - zero coverage.
3. I reposted an article from another popular thematic page - the coverage of this repost is zero.
4. Tried to advertise a post with a link, paid reach appeared, organic did not.
