Our main recursive nameservers are running BIND 9.6.1-P1 and are using
DNSSEC validation via

We had a report this morning that names under were failing to
resolve. I suspect that these were SERVFAILs, although unfortunately
the situation had corrected itself by the time I was able to look at it.

It is maybe not coincidental that a (perfectly correct) DLV record for appeared today. Does 9.6.1-P1 have known problems with
insecure->secure transitions of this sort? (I seem to recall similar
problems being reported with substantially earlier versions.)
