I haven't tried this yet, but I have figured out that it's not actually my
ISP's DNS servers that're at fault. Somehow, the requests just never reach
the server, since I tried different DNS servers and they all exhibit the
same problem, again both under Linux and Windows.

It also definitely has nothing to do with lag between me and the server:
Tracing route to sherlock.leidenuniv.nl [132.229.8.6]
over a maximum of 30 hops:

  1 2 ms 2 ms 2 ms
st1.student.leidenuniv.nl.236.229.132.in-addr.arpa [132.229.236.1]
  2 2 ms 2 ms 2 ms sherlock.leidenuniv.nl [132.229.8.6]

Trace complete.
