The cloud storage services company was formed in 2008 and raised $32 million-plus in funding, only to shut its doors in 2011. The company had also raised high hopes, even making Network World's 2009 list of hot startups to watch. However, the cloud storage services market has remained a murky one, with larger players such as Iron Mountain and EMC also pulling back on their offerings. Cirtas did indicate in April, when its shutdown took place, that it could be open to a re-launch in the future. But for now, the company's website has disappeared and signs aren't good.
