Notification of upcoming scheduled maintenance periods: April 5th and April 20th

[App Engine Downtime Notify]

Hey everyone,

(If your application uses High Replication datastore, you can ignore
this email)

Just letting you all know that we're planning two upcoming scheduled
maintenance periods in April:

Monday April 5, 5 PM Pacific
Wednesday, April 20, 5 PM Pacific

We usually try not to do more than one scheduled maintenance a month,
and we only resorted to spacing the maintenance periods so close to
each other because there are no feasible alternatives. The good news
here is that it should be a while before our next read-only period.

Below is the standard information we usually send out with these
notifications. Check it out for more information about read-only
periods or how to be notified of production events.

The datastore will be placed into read-only mode and memcache will be
flushed. It is recommended that critical portions of your application
that depend on the datastore 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

There will be no downtime for developers whose applications use High
Replication Datastore. You can read more about High Replication here:
