Hi, I tried to spin up a relay on GCE a few days ago, and I found that it was outright rejected with a message like "Authdir is rejecting routers in this range". I don't have the IP handy now, but I could easily get another ephemeral IP. I thought I came across a thread saying that there was an attack on the tor network originating from GCE, and that's why it got blacklisted. I'm not finding that thread now. But is GCE going to be removed from the blacklist? I realize it's not a very economical place to run a relay.

I think this is from the Lizard Squad attempted (and miserably failed) sybil attack. The directory authorities will need to remove the ASN from the blacklist.

If that's the case, then that was a year ago. Hopefully directory authorities would be okay with removing the ban. Is there a process for requesting that?
Thanks, Greg

Hi Greg,
I have forwarded the request to the relevant people. Please stand by to get an update about it as soon as possible.

I wonder if we wouldn't be better off with GCE remaining blocked. Cloud platforms seem quite popular among attackers -- presumably because they can quickly give you a large number of disposable machines. Naturally, there will also be benign relays running on cloud platforms. We might have to do some number crunching to ponder if the benefit of having these benign relays outweighs the potential harm of attackers being able to use GCE et al.
Second, and perhaps less obvious, Google is already in a privileged position as many exit relays use Google's public DNS server as resolver. If GCE machines end up being guard relays, Google might be able to correlate some DNS requests of the Tor clients that end up selecting GCE guards.
Cheers, Philipp

Similar thoughts. Feeds into the idea about some meta metrics on relays users might select from... WOT, location, etc. Maybe they even want the cloud due to having really good pipes.
There are certainly plenty of non-mega-cloud VPS/dedi's to choose from out there, even in people's local cities. Just look around, form a relationship, not a billing statement.
Thanks for the responses, s7r, Philipp, grarpamp. I can see the benefit of keeping the biggest cloud providers on the blacklist. But if that's considered to be the best practice for Tor, are Amazon and Microsoft blacklisted as well?
I am actually looking into a VSP from the "good/bad ISP" list, so I will probably go with one of those. I thought I'd just try out a remote relay on GCE to start with.
