Putting up an announcement on (sigh) the pool webpages that we have no
tr zone (and perhaps giving some subtitute, tr2 maybe?) and explaining
why would, it seems to me, break the abusive access while being about
as minimally disruptive as possible to others.
Considering the quality of the code in those routers, removing the DNS
name that
they are looking for will probably result in a DOS attack on the DNS
servers.
This is unlikely. Since the provider's DNS resolvers will only query the
pool.ntp.org DNS servers once, and then wait until the TTL runs out. So
there might be a heavy load on DNS servers, but most likely on the
servers of Turk Telekom. And if the clients only ask once and wait for
the TTL to run out, even this load will be the usual load.
