exch.net is not working because it has been suspended.
Domain Status: clientHold http://www.icann.org/epp#clientHold
This could only have been done by the domain registrar, likely at the request of law enforcement.
Based on the official statement from eXch (
https://bitcointalk.org/index.php?topic=577207.msg65286839#msg65286839)
The shutdown of the eXch was not executed by a domain registrar at the direct request of law enforcement, but rather was a voluntary closure by the exchange's own management in response to overwhelming legal and enforcement pressure from international authorities.
Furthermore, eXch emphasizes that it does not want to operate "
where we are viewed as criminals" and stresses its ideological commitment to privacy and decentralization, n
ot illicit activity.Note: There is no evidence in either the official statement or the news coverage that the domain registrar executed a takedown at the direct request of law enforcement.
