Here’s a strange one - we have a cluster using rancher/nginx-ingress-controller:nginx-1.2.1-rancher1. Been working great. All of a sudden, we’re seeing horrific ingress times upon first page view (browser is idle for upwards of 90 seconds before data is transferred). After this really slow load time, page responses to the same ingress are really fast. Seems to only be impacting a single cluster right now, other clusters using the same image are fine. And the controller logs are completely empty other than certificate expiration warnings.
