What's your personal experience with it? We've been on the platform for almost eight years. Three clusters, hundreds of compute VMs, four or five public and private DNS zones, 10+ cloud sql dbs, about the same number of memorystore and firebase instances. We just don't see these issues as related in the OP, and when we do have problems support has been fast and helpful. Not to gainsay their experience, since it was obviously frustrating, but truthfully you can find similar stories about all compute providers.
