Google App Engine开始收费，可以超过之前的配额。

不过90天后，免费的配额会有所减少。

App Engine will always remain free to get started. However, along with many performance improvements, we have learned that we were overly conservative with our initial free quota estimates. Therefore, 90 days after February 24th, 2009, we will be reducing the free quota resources.
