You might be interested in learning that we do things in a bit more
sensible way: we store data that's rarely accessed, such as the data
served by our rsync server, on cheaper, rotating hard-drives.
Hopefully this helps you freak out less about this topic :)

Agreed.

It's actually very simple: everything is mirrored.
We still tell mirror operators that they can exclude the "obsolete"
directory if they wish, but we've deleted it on our side months ago,
so I'm going to drop these bits from the doc.
So, anonym: please either do this immediately after reading this
email, or give yourself a ticket so we don't forget about it.
I also thought that a monitoring check might be useful, but IMO it's
overkill as we can solve this much more easily, and closer to where it
should be fixed if a problem is found, in the release process doc.
