Thanks very much Nicholas, Can I first say how great it is to have Google Cloud Support here helping us out! I know it can be a tough job dealing with people problems all day. I really appreciate it and I'm sure there are many others that do as well!
1. The images are all hosted on App Engine and are is a static directory specified in the app.yaml. I also server stylesheets, fonts, sounds, and scripts the same way and they all seem to be slow downloading. 2. I have noticed some slowness for a few weeks, but last Sunday the game was virtually unplayable because of the slow images. Since then, it seems to be intermittent. The 400k Images above is now loaded on my system in less than 4 seconds. (still seems kind of slow to me - but better than 8 seconds of yesterday) - To get these times I'm using Chrome Devtools Timeline. I might see if I can write a script to monitor how fast it takes and get some actual data rather than relying on anecdotal memories. 3. Yes it appears to be all images and all static resources. Yes I believe it's all users affected. 4. when you say "testing requires consistent results", what might the problem be if we did have consistent results?
