Chris DiBona, Director of Open Source of Google just announced yesterday that Google will close its code repository service in about ten months and stop accepting new repo creation. They also provide some migration tools for developers:
Google Code to GitHub exporter tool: http://code.google.com/export-to-github
Stand-alone tools: https://code.google.com/p/support-tools/
It quite a memory to me that Google Code is the first free repository service I used since I still was a student. It's not as great as Github but it's the only one available back then.
