 Replying to [comment:8 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.
