I was informed by some bot of removal of wikipedia page about Codeforces.
It was created some years ago when someone asked why there still is no such page. Then some material was added to it by few people, but it seems that either notability criteria were not reached or some other factors were involved (Russian hackers hysteria, maybe).
It is somewhat strange for me, since Codeforces is steaming extremely well, seemingly surpassing Topcoder by popularity and many other sites moreover.
Perhaps some people will decide to invest time and recreate/improve such a page. For now let there be the link to one of the latest snapshots of the page from wayback machine:
