Route request to specific instance

Does anybody know if GAE provides a way to route a request to a specified instance? The startup of new instances is killing me on facebook URL linter requests since they timeout before a new instance can start up sometimes. I have no way to control this timeout either. So what I'd like to do is to keep specified instances idle for these calls without needing to hack around it with cron jobs. I think this would be more cost effective as well.

The new modules allows for direct addressing of instances. Much like how backends used to work.

Like so:

This is not possible for frontends, but you can have requests directed to specific backends, and you can make backends externally accessible if you choose.

I'd suggest working on your app to improve loading time, though. If it's taking so long a bot gives up, that's got to have serious implications for usability by your users. Also, make sure you've got warmup requests enabled.

It sounds like you need a dedicated set of "always alive" instances to handle just those calls. Backends might be a good solution for that. You can set a separate url address to route to a specific backend.
