Re: [tor-relays] Tor Weather (was: Relay advocate introduction)

[Colin Childs <colin@xxxxxxxxxxxxxx>]

Hello Nusenu,

Thank you for bringing this up and filing the ticket, this definitely sounds like something that should be brought back in some form. I’m going to look things over, review the history of Tor Weather and then make a plan for moving this forward. 

A monitoring service (like Tor Weather) has also been requested from a few other operators as well; so I think this is definitely something that will make the community happier as a whole.

This will increase the likelihood that relay operators notice problems and actually mitigate the problem otherwise there is no "user feedback" since tor can cope with disappearing relays quite well.
