Between June 24-25, the nodes in Tectonic clusters running on Azure automatically updated the OS from Container Linux 1353.8.0 to 1409.2.0. After this upgrade, the nodes began to experience increased latency and failure rate in requests. Interestingly, we found that the size of the HTTP request played a role in determining the success of requests to services running on the Kubernetes cluster. We found that setting the client's interface's MTU to 1370 made all requests succeed; incrementing the MTU to 1371 caused the failure of large HTTP requests to resurface. Additionally, enabling TCP MTU probing on the clients ensured all requests would succeed, albeit with increased latency. In order to identify the minimum set of circumstances needed to reproduce the issue, I ran several tests involving different network topologies.
