We just released a change to simplify how we manage disk space for open source projects hosted on Google Code.
Previously, we enforced disk quota on a component-by-component basis. For example, source code used to have a 2-GB limit and downloads used to have a separate 2-GB limit. As of today, we’re announcing a single disk quota limit of 4 GB for an entire project. From now on, you can decide how to best use the unified quota across your whole project.
