I am quite sure it was DNSSEC in Knot DNS.  Especially with on-the-fly signing.

Now I am waiting for the same thing in in OpenSSL for BIND 9 ;).

The ECDSA is too fragile when weak PRNG is used - think of spinning multiple VM guests with the same seed from the image.  That might leak private key pretty quickly if the timing is right.
