Thanks for that.  trinite.co.uk are going to correct their entries.

However our inability to lookup bc-bucharest.bcouncil.org without first
caching bcouncil.org remains.  One thing I unfortunately neglected to
include in my original message was the log from any failed lookup of
bc-bucharest.bcouncil.org ...

Sep 21 12:17:32 cblslca named[27148]: ns_resp: query(bc-bucharest.bcouncil.org) Glue A RR missing (NS1.TRINITE.CO.UK:)
Sep 21 12:17:32 cblslca named[27148]: ns_resp: query(bc-bucharest.bcouncil.org) No possible A RRs

this is against their unchanged entries.
