Yes, Moritz is right - you can correlate server downtimes when services run on the same server. When tor runs both a relay and onion service, you can correlate at least: guards, event loop delays, and server downtime. I think there are also other security issues involved, which is why we don't recommend this configuration. Tim Tim Wilson-Brown (teor) teor2345 at gmail dot com PGP 968F094B ricochet:ekmygaiu4rzgsk6n
