GigaOM: RackSpace IPO Filing Hints at Expansion Plans. Data center and hosting provider RackSpace Inc., has filed to raise up to $400 million in an initial public offering. Its financials seem generally sound (unlike many tech companies it’s actually profitable), although profits did drop by 10 percent in the last year.

I’ve added Rackspace Inc. contracts. Rackspace had included several employment agreements and economic development agreements in its filings.
