App Engine Latency up 100x

[troberti]

Anything going on? Our apps latency has increased about 50x to 100x. Most requests take over 5 seconds now, some over 10seconds. Usually its just a couple of 100ms. This has been going on for the last 3 hours.

The app-id is firipx if someone is interested in taking a look. No changes on our side I should add.

Also seeing way more warmup requests than usual, about 5% of those are aborting with the ominous error '121':

E 00:47:39.821 A problem was encountered with the process that handled this request, causing it to exit. This is likely to cause a new process to be used for the next request to your application. (Error code 121)

Is this issue still ongoing for you?

Thankfully no. It 'solved' itself after 4.5 hours. No actions on our side (redeploys etc).
