May be this is releavant ? : Reminder: there will be a scheduled maintenance period for App Engine TOMORROW, May 5th, at 1:00 PM Pacific Time (PDT) 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. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
