A comment on Tor: From the Dark Web to the Future of Privacy. Parent comment
DoS'ing a server and correlating timeouts is a well-known but still discernible technique.
Random delays and packet data have been added to help bugger against this and timing/padding/other side-channel attacks.
At this point most servers operate multiple random timeouts + blackouts + array of mirrors/jugglers to mitigate this de-anonymization technique.
