Lou Reed - Transformer

Data center transformer blow up at Qassia
2008-06-07 06:12:00 You may have noticed that Qassia, the powerful and free SEO tool for feeding backlink oomph to your websites, was not available for about 24 hours over the weekend. This is because a transformer at the data center blew up, taking down 7000 servers. Qassia always did refer to itself as an explosive and dynamic startup, but didn't quite mean it in a literal sense. Anyway, more about the explosion on Qassia Updates page. http://admin.qassia.com/updates-The outage occurred, typically, just after Qassia released two new and crucial features, Alerts and the Watchlist. Check 'em out, they're in your dashboard. Qassia has a major announcement scheduled soon. Meanwhile, Happy SEOing!

Current Transformer (CT) polarity

While the others cross functions in the same space (like the living room), this quaint concept is more of a comfortable suitcase, or chair with wheels that holds a bunch of clothes sometimes. By crossing platforms, it insures that there are few situations that it couldn't be functional; the only bummer is that it looks like it has to be a suitcase full of clothes, or a chair (without the clothes) and not both.
