EFF: One Year Later, Hundreds of Tor Challenge Relays Still Active

The Electronic Frontier Foundation reportsthat 567 relays from the 2014 Tor Challenge are still up and running-"more than were established during the entire inaugural Tor Challenge back in 2011. To put that number in perspective, these nodes represent more than 8.5% of the roughly 6,500 public relays currently active on the entire Tor network, a system that supports more than 2-million directly connecting clients worldwide."
