一个托管在GAE的网站打不开，刚好是要和别人交换友情连接的时候，提示以下错误信息：
<type 'exceptions.NameError'>: global name 'g_blog' is not defined Traceback (most recent call last):
连接PPTP VPN，登陆appengine.google.com，通过dashboard可以看到有红色警告“

”“Your application is at or near its free resource limits”
而且还提示说”Quotas reset every 24 hours. Next reset: 16 hrs”，哎，还是修改DNS吧，这样还快一点！
