Wii U update blocker DNS doesn't work?

[Erencikefe]

Hello, i have a problem with my dns setup on my wii u internet connection. It used to work, but now when i type the dns that block updates it blocks the whole internet and doesn't let me connect to internet. Is this normal? Are the servers down?
