Around a month ago several networks - SEO Nitro (Dori Friend), HomePageBacklinks.com (Terry Kyle), Backlink Monster (Brad Callen), etc - got largely deindexed by Google. As soon as that happened we locked down HPS to new users, changed hosting, and went underground as best we could. Our goal was to protect the service for our users and ourself.
Unfortunately, a few days ago our luck ran out. A bit more than half of our sites were deindexed. We've seen sites drop and come back, but I don't think that's going to happen this time.
