How often do they tend to restart usually? (For instance, I'd be unsurprised to hear e.g. that Roger tests his commits on his dirauth, and so that server never has high service uptime, or something.)
i don't want to speak for roger, but my general understanding over the past few years was that roger typically appeared to run fresher alpha code on a sister relay named moriatoo (https://atlas.torproject.org/#details/5C91CC4554CA2EE1904BA6...) before upgrading moria1.
but at the moment, moriatoo is running 0.2.6.0-alpha-dev and moria1 is running 0.2.6.1-alpha-dev
