Hi all,
We will be taking memcache offline tomorrow morning from 9-10am PST
(GMT-8) for routine maintenance. 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.)
Your app should continue serving normally during this period, and
we'll keep you updated on our progress.

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.
