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.

But the content is still available isn't it: https://code.google.com/archive/

When people try to self-host and get lazy or hit by a bus, the content just disappears unless it was lucky enough to get archived.

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.
