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.
