Description

The directory mirrors trusted, blutmagie, and vallenator all report very low dirreq-v3-share values in their extra-info descriptors since late May 2010 (see here).

We were able to identify the introduction of bandwidth-weight values in consensuses as cause for these low directory request shares. See the graph in the attachment. The more consensuses on a given day contain bandwidth-weights (up to 24), the lower are the reported dirreq-v3-shares.

A fix is suggested in #1564. In addition to that, we should calculate shares from descriptors archives rather than believing in what relays say.

Milestone: Calculate directory request shares

Removing the milestone. This isn't how milestones are supposed to work. "Calculate directory request shares" is a task or maybe a project, but not a milestone. The next time we should use a parent ticket instead. I'm not creating one now, because nobody cares anymore.
