Swedish ISP forced to block Sci-Hub by Elsevier also blocks Elsevier

Good that an ISP has the balls to do that.

On a technical note: is this kind of censorship at DNS level, where that ISP's default DNS servers return a different ip for the blocked sites, or is it one level deeper and using third party DNS won't help?

Good for them, I wish more ISPs were on their actual customers' side in matters like this.

Original title "Swedish ISP punishes Elsevier for forcing it to block Sci-Hub by also blocking Elsevier" was slightly modified to fit the title length requirement.
