So slight postmortem:

The url per e-mail depended on the order of processing for messages:
the first message got 1, the second got 2 and so forth.  The upgrade
ruined that database.

To prevent this in the future, Robin created a scheme that is not
dependent on the order of processing (which is harder that it sounds
as we discussed on -infra last night).  We don't have a mapping from
old e-mails to new ones.  If you know what the title was you can
probably fish the message out of the archives; otherwise you are
probably SOL.

The bonus out of all this is that the new storage format could get
destroyed and we wouldn't have this problem (archives would just be
down for two days while infra regenerates the indexes.
