We've had some short notice of required maintenance on some of the sub-systems of the editor.
At 11:00AM Pacific the Google Mashup Editor will go into read-only maintenance mode for approximately 3 hours. Only the Editor will be affected. You will be able to login and view the source code of your applications but you will not be able to save until about 2:00PM Pacific time. Your published applications will not be affected by this maintenance.
We apologize for the short notice.
