Reminder: Upcoming scheduled maintenance November 6th, 2010

[App Engine Downtime Notify]

This is just a reminder that there will be a scheduled maintenance
period beginning on Saturday, November 6th, 2010 at noon Pacific Time
(November 6th, 2010, 19:00 UTC) lasting one hour. During this period,
the datastore will be placed into read-only mode, while Memcache
contents will be flushed.

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

The scheduled read-only period is beginning right now.

Applications should be able to perform datastore writes now. We're
still not finished with the maintenance and will post another update
when we have completed work.

The maintenance work has been completed. The datastore was in a read-
only period between 12:02-12:45 for a total of 43 minutes. Some users
reported two periods of 500 errors unrelated to datastore writes, but
these issues should no longer be occurring.
