This doesn't strike me as an effective demographic to "full on censor" in this way. Generally speaking, people interested in hacker conferences know how to proxy around a net nanny. Could this be a botched poor-mans wiretap?: i.e. traffic sent to black-listed domain get's transparently routed to an adversarial middle host, who is intended to eventually forwarded it on to the original destination, but in this case someone misconfigured the wiretap, causing traffic to get lost. (/tinfoil hat) I'd like to see the tracert for other hosts near the same destination.
