Pods loosing connection to each other is still very very common in azure.
To see the positive side of it, it’s a Chaos Monkey test for free. Everything you deploy must be hardened with reconnections, something you should be doing anyway.
What’s frustrating is that it happens rarely enough to give the illusion of being stable, making it easy for PM to postpone hardening work, yet often enough to put a noticeable dent in your uptime if you don’t address it. Perfect degree of gaslighting.
