What does premature EOF, fetching "some_zone" mean?

It means named-xfer has given up trying to read data from the
network. [Check the source code where this error message is printed.]
Usually this happens because other end of the TCP connection for the
zone transfer has gone away without shutting it down properly.

FWIW the behaviour of the name servers for mytestdomain.com is
odd. Zone transfer requests to them fail, but no error is
returned. The servers accept inbound queries on TCP connections, so
it's not a connectivity problem. If the servers were rejecting
unapproved axfrs, I'd expect them to return a REFUSED response code.
