YCombinator is listed as in the Rackspace Startup Program [0] - I'm on my phone so I haven't had a chance to do due diligence, but is HN hosted on a Rackspace server?

HN is hosted at SoftLayer in Houston, TX. The IP block and reverse DNS indicate hosting by ThePlanet; ThePlanet merged into SoftLayer.
