COM. and NET. zone files were corrupted.

a-g were affected by this corruption, h-i did not take the
corrupted update (perhaps they're otherwise broken), and j-m
do not serve the affected zones.

a was finally corrected at 6:55am, and admins of b-g
were asked to reload their zones. It appears that none
of said admins have done so to date.
