High latency trace requests to non-existent versions

[Blaine Garrett]

Apologies for pre-maturely sending previous message. 

In the GAE dashboard, I'm seeing a lot of high latency traces with URI "empty"

When I look at individual traces, I'm seeing the hosts are mostly non-existent GAE versions). I use a custom domain, so it is odd to get any traffic to a version URL.

When I search the logs, I do see some traffic to these URLs from Google Bot.

Latency is in the 16000ms range which does not seem to happen when hitting "/" the browser, so it is odd.

So I have a couple questions:

* Is the empty URI merely the "/" url of the app and the latency is just a slow page (probably instance startup)  or is there something else going on? 

* Is there a way to prevent traffic to previously deleted version urls? If some/all of the traffic is coming from Search Bots, I do not want those versions indexed.

I have a NodeJS client with python 2.7 standard env for the default module.

Thanks in advance.

Google Groups is meant for general product discussions and not for technical support.

I highly recommend you report this in a Google Issue Tracker. Just make sure you provide more information such as your project ID, and the timestamps (with time zone) of these requests to non-existing versions so that we may investigate this further.

Morgan from the Stack Driver team reached out to me about the "empty" URIs. This was a known bug.

I'm still curious as the best approach to prevent traffic to non-existent versions.

I'll file a ticket. Thank you.
