During my time there, the stuff was amazingly solid. It was Solaris, not Linux, with a heavy dose of NetBSD ports. The customer support was the best in the biz too, but only the larger customers really saw that.

There were always those legacy customers from years before who had there stuff running on some boxes in an old datacenter that only a few of the original staff knew about, and required continuous care and attention. Ihere's a business lesson to learn there - if you sell a "lifetime" subscription for a product that will become obsolete, you'll pay a lifetime PR cost in the future when you can't continue with that product.

Coming from a pretty long Linux background, Solaris took some getting used to, but once I figured it out, it really was a better, more solid, better engineered solution. But Linux has a huge community - the people that loved Solaris are the old Unix graybeards, and that community wasn't growing.

Before my time, there were some debacles, such as a storage platform product that ended up losing data, but by the time I was there, they had learned the lessons, and I'll still say their core stack is still superior to any Linux based stack used in the datacenter today. It's been 4 years since I worked there.
