Today my app had a serious problems for a couple of hours. I am trying to understand what went wrong and how to prevent this in future. I think this was a problem of appengine and memcache service was not responding for a while. I am making a conclusion like this because in logs I find a big number of requests which died like this:
<...> File "/base/python_runtime/python_lib/versions/1/google/appengine/api/memcache/__init__.py", line 619, in __get_hook rpc.check_success() <...> File "/base/python_runtime/python_lib/versions/1/google/appengine/api/apiproxy_rpc.py", line 119, in Wait rpc_completed = self._WaitImpl() File "/base/python_runtime/python_lib/versions/1/google/appengine/runtime/apiproxy.py", line 131, in _WaitImpl rpc_completed = _apphosting_runtime___python__apiproxy.Wait(self) DeadlineExceededError However http://code.google.com/status/appengine<http://code.google.com/status/appengine/detail/memcache/2012/01/29#ae-trust-detail-memcache-get-latency> does not show any problems. So I am not sure. Here is todays graph with milliseconds/request: <https://lh4.googleusercontent.com/-q9PdPRkd_e0/TyW94risJeI/AAAAAAAAAA8/vJSeaBgCawk/s1600/disruption.png> If this was a problem of appengine how can I prove that and how can I get a refund for resources wasted by many instances which where started during these hours? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
