Quite possibly because it's not running powerdns at all, it's running 
bind 9 - or at least claims to be.

$ dig +short @ns6.convergent-ict.com version.bind txt chaos
$ dig +short @ns7.convergent-ict.com version.bind txt chaos
"PowerDNS Authoritative Server 4.2.1"

Maybe what has happened is that someone has installed/started bind on 
that server, it bound to port 53, and this in turn is stopping powerdns 
from starting.

BTW, this makes it very clear why the "out in the open" support policy 
is so important! :-)

Also, do note that powerdns 4.2 is due to go end-of-life soon:
