Ask HN: What was the HN thread on building own server for photo start-up?

Hi! I was wondering what was the HN thread about some photo start-up building own servers rather than using AWS because own infrastructure was about a third the cost of using Amazon S3 for storage.

I have been Google-ing for many hours and used "site:news.ycombinator.com" along w/ date-range and several keywords, but was unsuccessful in finding that post.

The post was a discussion here on HN + link to a blog post on the company website. I cannot remember the name of the company, but I think it began with the letter "C".

Here is some things that I found that are somewhat related to what I am looking for but not exactly want I want: - http://news.ycombinator.com/item?id=2786066 - http://news.ycombinator.com/item?id=3099796 - http://news.ycombinator.com/item?id=332624

The post was made several weeks ago (I think - so fairly recently). I would really appreciate it if you can help me in finding it. Any suggestions would be greatly appreciate it. Thanks!
