I was thinking, one could use switch.ch as a DNS. They claim to be based in Zurich, but seem to have an emphasis on educational sites.

They are actually based in Zürich (I take the tram past their building each day). I don't think they do DNS though. They don't just do educational domains, though they do focus on that domain (no pun intended).

switch.ch registers domains, but I couldn't find a reference to them offering DNS. They also have steep prices and a very limited selection of TLDs.

Steep prices shouldn't deter anyone who's looking to build a takedown-proof site.
