How did you establish that there is maintenance happening almost everyday, on your Cloud SQL instance? Disruptive updates generally only occur every few months. 

If you think there is a problem with your Cloud SQL instance, your are encouraged to open an issue in the Public Issue Tracker, where communication can be set to private, and your project examined thoroughly for specific issues. This discussion group is oriented more towards general opinions, trends, and issues of general nature touching App Engine and Cloud SQL. For MySQL instance related advice, you may be better served in dedicated forums such as stackoverflow, where experienced programmers are within reach and ready to help.
