We did have stability issues. Of course, I believe that all of the issues were self-induced. IBM support was able to advise, as well as modify, my instance of dashDB in order for maximum performance.

In the very beginning, we had some stability issues but that was more due to a misunderstanding on the licensing side than due to the platform itself. Since then, it's been up 99.9% of the times.

At the start of the project, the customer had difficulty with connecting to the dashDB instance. After IBM recreated the dashDB instance, it worked fine.

In the first year, we had multiple issues with stability of the service. We started with a cloud-based shared instance with limited data space. Once our PoC was done, we moved to a dedicated instance with high availability and better SLAs.

Yes, containers get corrupted very easily. Restoring them using GPFS can result in a lot of issues.
