So were vast numbers of other sites, as their brokenness didn't become
apparent until DNSSEC started being used.

We were running EDNS-enabled nameservers for ages with such a "broken"
network configuration: non-initial UDP fragments were being dropped at
the border router to the university network (in response to some ancient
DoS scare). It took DNSSEC (the IANA testbed, in particular) for us (well,
Tony Finch, actually) to notice.
