I was really hoping to start using PortSensor, but don't seem to be having much luck.
All documentation (i.e. the wiki) appears to be unavailable at the moment. In fact, updates.portsensor.com appears to be down too, so maybe it's a problem common to all of your subdomains? I'm using OpenDNS, which confirms the lack of availability worldwide - see http://www.opendns.com/support/cache/
So, I email support@portsensor.com and the email bounces back to me!
...and now in the last couple days, the Cerb4 Blog has disappeared (after I left a comment asking whether PortSensor was still alive). Wow, sure seems like everything is coming down piece by piece?
Hey guys, PortSensor is indeed alive! we had a few DNS kinks to work out when we migrated the site recently, but the wiki is back up. Development has slowed on the current version since it's grown stable but we plan to revamp things quite a bit by making a more distributed implementation and offer it as a service in the future.
