Right. The jigdo and template files themselves are replaced every Monday (typically) as part of the weekly build setup. However, the .deb and other files that are referenced may drop out of the Debian archive much more quickly, depending on testing migrations. This is why we have the snapshot server as a fallback. >As far as your point of using the snapshot archive at the very last, >when does that happen or how many hops or services it has to try >before hopping onto snapshot service. It should fall back automatically AFAIK, but it's a while since I've looked at the code in jigdo-lite to be able to tell you exact details of how and when. So, testing with an old jigdo file I have easy access to... Yes, it should get there, but only when it's tried and failed to download all the files that are missing from the normal mirror: ... --2011-09-05 17:51:30-- http://ftp.uk.debian.org/debian/pool/main/m/mkvmlinuz/mkvmlinuz_32_powerpc.deb Reusing existing connection to ftp.uk.debian.org:80.

The jigdo file is simply a text file, normally gzipped - use zless or similar. -- Steve McIntyre, Cambridge, UK.
