Reminder: Scheduled Maintenance, April 28th, 1:00 PM Pacific Time

[App Engine Team]

Reminder: there will be a scheduled maintenance period for App Engine
next Wednesday, April 27th, at 1:00 PM Pacific Time for up to one
hour. The datastore will be in read-only mode during this time period;
all datastore writes and transactions will throw an exception.

During this scheduled maintenance, memcache will also be disabled.
Calls to the memcache API will not throw exceptions but will instead
return False for set() calls and None for get() calls (just like any
other cache miss). In addition, memcache API calls will return
immediately during this period, without any additional latency.

It is recommended that critical portions of your application which
depend on datastore writes are modified to gracefully degrade. Links
to our documentation with code samples are below:

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