He did say i386 CD images, and duplication :-)

Not yet... Maybe what follows hasn't been done yet because of the
holidays so please take these observations just as reminders.
First, if the checksums files have been changed a trigger should have
been sent to the mirrors registered for push syncing. Also, the trace
file of the archive should have been updated.
Second, this incident shows that the generation of the checksums isn't
properly automated. This is an important responsibility of the master
archive. And it's too heavy a task to ask the mirrors to verify
checksums of 378GB... For the [few] mirrors that create the images
locally, jigdo-file is very careful and does [a lot of] its own
checksumming, so even in this case it's not necessary for mirrors to
use those files. That said, some of the mirrors that update faster
could check to catch problems early. I could do it here on request of
the master admin.
