Notification: Upcoming scheduled maintenance periods September 13th, 2010, November 1st, 2010 and December 6th, 2010

[App Engine Downtime Notify]

We are scheduling three upcoming maintenance periods:

September 13th, 2010 - 4pm-5pm Pacific Time (Sept. 13th, 23:00 UTC)
November 1st, 2010 - 4pm-5pm Pacific Time (Nov. 1st, 23:00 UTC)
December 6th, 2010 - 4pm-5pm Pacific Time (Dec. 7th, 0:00 UTC)

During the one-hour maintenance periods listed above, the datastore
will
be placed into read-only mode and memcache will be disabled. Calls to
the Memcache API will return None or False for write operations,
while
read operations will behave as cache misses, returning immediately
without additional latency. It is recommended that critical portions
of your application that depend on the datastore or memcache should
make use of the capabilities API to detect and recover gracefully
during read-only periods. Documentation describing the capabilities
API can be found here:

Python: http://code.google.com/appengine/docs/python/howto/maintenance.html
Java: http://code.google.com/appengine/docs/java/howto/maintenance.html
