Where do remote topics live?

I decided in the evening to look at the answer to the problem with dividing the figure into two equal honors ...
I look and the topic is not 404 habrahabr.ru/blogs/zadachki/70573
He stumbled around and noticed that it appears that deleted topics in the mobile version continue to live m.habrahabr.ru/post/70573

ps Moreover, there you can see all sorts of artifact topics like this m.habrahabr.ru/post/9205

UPD Topic opened, closed the hole (and Saturday, however!)
