Moving https://trac.torproject.org/projects/tor/ticket/21378#comment:12 into a separate ticket: Quoting teor: > Replying to teor: > > Replying to irl: > > > Using the fixed URL ​http://<hostname>/tor/status-vote/next/bandwidth.z sounds like it would be very easy to add this to CollecTor. > > > > Thanks for the feedback! > > > > > We have discussed in the Metrics team extending `dir-spec.txt` to allow to fetch "recent" files as well as just next/current. In the case that there is a wide CollecTor outage, and we miss a file, it would be good to have those files cached (on a best-effort basis, not necessarily persisted to disk) and available via some URL. > > > > How is this any different to losing descriptors or consensuses? > > (Please answer this question on a separate ticket.) > > > > > I don't know if karsten already had some ideas about what these URLs would look like, but we should perhaps consider this before implementing changes to `dir-spec.txt`. > > > > Please open a separate ticket for this feature. It's potentially a large feature. And it's not essential for the initial release of this feature. > > If you open a separate ticket for historical directory documents, please make legacy/trac#26698 a child of that ticket. We'll need bandwidth file hashes to work out the exact file used in each vote.
