We are currently investigating an issue with an underlying component that affects both Google App Engine deployments and Memcache availability. Deployments will fail intermittently and memcache is returning intermittent errors for a small number of applications. For affected deployments, please try re-deploying while we continue to investigate this issue. For affected memcache users, retries in your application code should allow you to access your memcache intermittently while the underlying issue is being addressed.

Work is ongoing to address the issue by the underlying component's engineering team. We will provide our next update at 15:30 PDT.
