The University of Waterloo's DNS is managed through Maintain.
People who have access to Maintain:
DNS service was terminated because it didn't work well (some problem with additional work needing to be done for some nameservers to accept delegating authority to us), nobody used it and it caused a potential security problem (which could have been fixed, but removing it was easier for the preceding reasons).
See an old revision of this article for more detail.
If we really cared, we might add a LOC record for csclub.uwaterloo.ca.
