なぜか memcache でエラーが発生するようになっている。
要観察

回復

Our memcache maintenance was completed at 10:52 PST (GMT-8). During
this period, although calls to the API did in fact return False and
None as expected, memcache API response latency increased
significantly, causing requests with heavy memcache dependence to time
out after 10 seconds due to the request timer, covered in our
documentation here: http://code.google.com/appengine/docs/python/requestsandcgi.html

We're now implementing a fix for this issue, and in the future the
memcache API will return immediately in the event of an outage. We
apologize for any inconvenince this may have caused.

datastore_errors.BadArgumentError:_app must not be empty.

以前 SDK で動作していた script が動かなくなった。

以下の一行の追加が必要

When I upgraded to 1.1.3 from 1.1.2, my App Engine unit tests (built 
using the scheme described in another post [1]) started failing with 
the following stack trace: 

google.appengine.api.datastore_errors.BadArgumentError: _app must not be empty.

I added the following in my test setup:
os.environ['APPLICATION_ID'] = APP_ID
