Hello Jonah,
First thing... the ticket you created is public ticket and it's open to internet. So may be we should be careful to share classified information.
Secondly, we need more logs ( i.e. network traffic etc ) to find out "why" number 1 is happening. I believe, there is some load balancer issue.
>> In summary, the service is unavailable for consistent use.
I agree... the whole setup is mind of mess somehow. That's why I am continuously requesting your management to go for upgrade with proper design and setup.
