No guarantees either way - Google Code was alive and kicking, until it suddenly wasn't.
I do appreciate how easy git and other dvcs make it to mirror repositories, though. I find myself using Github mirrors of projects that are otherwise self-hosted, just because the code search works on Github works pretty well.
Funny, I find myself cloning GitHub repos just because code search on GitHub works pretty badly (e.g. it doesn't pick up partial tokens). Haven't had the chance to compare to other solutions though.
