That's my guess.  1.0.0.0/8 was one of the last network blocks
allocated--last April, IIRC--and prior to that time it was often
filtered because it was commonly used in spoofing attacks.

In fact, the BIND 9 documentation contains a sample blackhole ACL
which, until recently, specifically recommended filtering addresses
in that block.  The advice is outdated but I think someone is still
following it.
