Answer:

You need to split the traffic to your test version.

Explanation:

Google app engine has a built-in feature that allows you to split a small fraction of your traffic to your test version.

You can split traffic using an IP address, so when the app receives a request, it can hash the Ip to a value between 0 to 999, and use it to re-route the request.

This way you don't need to stop your service during your tests and also avoid any risk involved with it.

A tornado may be approaching if you observe which of the following?
musickatia [10]
I would go with a funnel cloud on this one. It is the most common sign although it does not guarantee a tornado. Most tornadoes that reach the ground do expand from funnel clouds, but a condensation funnel cloud formation is not absolutely necessary for a tornado to form.
