This is the downside of “cloud services”. It’s all sunshine and rainbows when it works. When it breaks, start praying and pull the wallet hoping that helps. You are just at their mercy because you cant look under the hood even if you want to. And it takes a long time before they decide to assign competent people on your case. My experience with Azure is pretty bad. (Premier) Support is next to useless. AWS is somewhat better, specially quality of their software/services/documentation. In my opinion, aws services feel more battle tested than azure. Sorry for the rant, back on topic. Do you have monitoring on the cluster? I would start to collect more low level metrics like open files, network traffic, pings Also what could help is to run daemonset of a pod that can send you diagnostics at regular intervals. Perhaps even capability for remote shell so that you can troubleshoot from within the node when the problem surfaces again. I would definitely be interested to know more how this turns out. I also run a fair share of AKS.
