No. Making bandwidth information public makes it easier to link onion services with their guards. It might also allow other kinds of attacks. We think it's safe to release a daily bandwidth figure for each relay. Or, more precisely, relays publish daily bandwidths so we can do bandwidth measurement and statistics. We don't like releasing that level of data, but it would take a lot of development effort to do it differently.
Relays are not anonymous. But individual relays can compromise the anonymity of clients that build paths through them, by making it easier for adversaries to find a client using that client's traffic.
I see screenshots of bandwidth on Twitter. And publicly available munin pages on relays. You might be surprised what people release.
Relays are not anonymous. Releasing detailed bandwidth can harm the anonymity of clients. See above. T |
