No issues with stability.

Based on experiences the stability can be fine most of the time. The system itself is pretty stable. Honestly, some of our solutions and the things we have deployed are not suitable for what should be used in the system. Suddenly we would deploy and reveal that there were problems there and we had made something wrong. It was just because of how we did it and our problems were more about not having enough knowledge. That's because of system inefficiency and lack of support. So I think the problems that we have experienced are not because the product in a sense is because of our lack of knowledge. In other words, we have seen lots of instability, but I think it's not because of the system.
