Why blocking banned sites may not work?

Question

Computer networks

Good afternoon. The question is strange. Previously, when entering the same rutracker, a stub from the provider opened in the tab, saying that the site was blocked. Now blocked sites open quietly, without any vpn. What's on the main PC, what's on the phone via Wi-Fi. Why can this be so? Is this some kind of error on the provider's side? On one of the forums I came across the opinion that this is a sign of surveillance.

Answer 1

Either the ISP has stopped blocking, or something between you and the ISP is lifting the block. This is possible with the help of fraud with packages. What it is - see for yourself what you have on the network, at home, in the office, or wherever you are. Perhaps someone slightly improved the home router so that it now bypasses blocking.
Of course, in theory it could be someone behind the router. But I'm not a fan of conspiracy theories. So I won’t guess whether this is surveillance or someone’s joke or mistake.

Answer 2

The provider already has all the possibilities for surveillance :) People work there (at the provider), they are wrong. I had such a case - instead of the blocking page from the provider, an indistinct "proxy error" from the same provider began to open, the user began to complain - they thought that this was a mistake of our proxy :D
