I don't understand any of this. Every atlassian product I have ever used has been terrible. All their software is full of performance issues, uncountable UI bugs, and every time we upgrade it's impossible to tell whether we lost any data in the process and several times we have lost data. Their continuous integration server, Bamboo, is pretty to look at but unusable except for the lightest of use cases. The message broker between master and slave constantly goes down, publishing artifacts is hit or miss based on various network conditions that are mostly out of my hands because we're in AWS and I think they use chunked encoding to transfer the artifacts.
Honestly, if they're worth $3.3 billion then the software industry is doomed. Maybe that's a bit over the top but the quality of the products based on what I read doesn't add up. How can you do so much R&D and still have a product that's so unstable and can't handle simple network hiccups?
