It’s worth knowing that there are no general Cloud Down issues that affect everyone. We are hosting individual ROS servers for each “Instance”. We have also limited resource usage (CPU, memory and disk) for every free instance, to ensure sufficient capacity for everyone and to ensure excessive use wont affect other instances. We did that after experiencing some heaving usage/testing on some instances which caused the autoscaling of resources to affect other instances. You might have experienced issues before this protection was added.
So individual instances can still experience issues if you are scaling up testing very quickly as we are limiting the capacity for each instance, and only manually adjusting that based on individual needs. We do get alerted when an instance is close to reaching resource limits and usually just add more capacity - but as that is manual, you may see a delay.
Hope this help clarify a bit? Otherwise let me know.
