I think pulumi will only check against its own state. Using a `pulumi refresh` command may update the state, so that on the next `pulumi up` the manually deleted resource will be restored.

Correct me if I'm wrong :D

There is also a command line argument `--refresh` which leads to a `pulumi refresh` before the `update` is executed

Ok, so `refresh` will go over and make sure the state is in sync what is deployed... good thanks.
