Basically, I experience network issues like what happened here: https://groups.google.com/forum/#!topic/google-appengine-downtime-notify/wiXNbETOYgA
On a regular basis, since if a request fails to reach App Engine, it's invisible to the logs etc. - It's impossible to detect or debug these issues either, I only learn about them from players/users They are usually regional too, while one player experiences the issue for a long duration, let's say 1-2 hours, the others usually have no issues When I open a support ticket, I'm denied any assistance as I'm on a Bronze level and refuse to purchase a package, and simply get directed to the Financial/SLA ticket url, and when I open an Financial/SLA Credit ticket, my claim is again denied as I need to have a Silver/Gold support package About the issue itself, I believe it's impossible to debug, for example, Cloudflare marks each request with a unique ray ID, so if a network request fails, it's possible to get the issue debugged from it's ray ID, but since App Engine has no system, what you have is just reports of 500 (Internal Server Error)'s that don't show up on any logs -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
