Re: [tor-relays] Running 5000 relays...

This sounds like a great effort. I wanted to point out 2 things: 1) I think that GCE IP addresses are blacklisted (due to an earlier sybil attack, https://lists.torproject.org/pipermail/tor-relays/2015-August/007656.html).

I don't think it is blacklisted currently (but maybe someone at the dir auth level can confirm that), see also this tor-dev thread: https://lists.torproject.org/pipermail/tor-dev/2015-August/009389.html

2) How do you see your work relating to and differing from the discontinued Tor Cloud (https://cloud.torproject.org/) project? I don't mean to discourage you, but I'm curious what the differences are.

cloud.torproject.org is dead.
