Hello, this was a planned maintenance window about which affected project owners were informed of in the form of a MSA email.
As you have pointed out the Managed VMs beta environment (App Engine applications deployed with vm: true in their app.yaml) is deprecated and will be turned down on December 15, 2017. The App Engine flexible environment is replacing Managed VMs, which we are no longer updating. During this turndown process, we will keep maintenance windows open, starting in October and running through the end of the year. This was one such maintenance window. Notifications leading up to each maintenance window will be in the Cloud Platform Console <https://console.cloud.google.com/>. For our beta customers, during this period, your projects will continue to be eligible for beta pricing in the env: flex environment (announced in November 2016). After Managed VMs beta is turned down, regular pricing <https://cloud.google.com/appengine/pricing> will apply. Please visit the upgrade guide <https://cloud.google.com/appengine/docs/flexible/python/upgrading>, and learn more about how to move from the vm: true environment to the env: flex environment. As detailed in the upgrade guide, the flexible environment does not support deprecated runtimes such as python-compat and java-compat. If you cannot yet upgrade to a supported runtime on the flexible environment, you can request to continue using a deprecated "compat" runtime on env:flex <https://docs.google.com/a/google.com/forms/d/1jD2Wa2fjvCjOSF8IOZdl38kxQHXhFl3wbRZG5jqARKQ/edit> t <https://docs.google.com/a/google.com/forms/d/1jD2Wa2fjvCjOSF8IOZdl38kxQHXhFl3wbRZG5jqARKQ/edit> em <https://docs.google.com/a/google.com/forms/d/1jD2Wa2fjvCjOSF8IOZdl38kxQHXhFl3wbRZG5jqARKQ/edit> po <https://docs.google.com/a/google.com/forms/d/1jD2Wa2fjvCjOSF8IOZdl38kxQHXhFl3wbRZG5jqARKQ/edit> ra <https://docs.google.com/a/google.com/forms/d/1jD2Wa2fjvCjOSF8IOZdl38kxQHXhFl3wbRZG5jqARKQ/edit> ri <https://docs.google.com/a/google.com/forms/d/1jD2Wa2fjvCjOSF8IOZdl38kxQHXhFl3wbRZG5jqARKQ/edit> ly <https://docs.google.com/a/google.com/forms/d/1jD2Wa2fjvCjOSF8IOZdl38kxQHXhFl3wbRZG5jqARKQ/edit> . <https://docs.google.com/a/google.com/forms/d/1jD2Wa2fjvCjOSF8IOZdl38kxQHXhFl3wbRZG5jqARKQ/edit>The compat runtimes will be available on this basis until flexible environment solutions for memcache and task queues are in public beta <https://docs.google.com/a/google.com/forms/d/1jD2Wa2fjvCjOSF8IOZdl38kxQHXhFl3wbRZG5jqARKQ/edit>. After receiving a confirmation email, you must follow the steps in the upgrade guide <https://cloud.google.com/appengine/docs/flexible/python/upgrading> to run your application on the flexible environment before we decommission Managed VMs on December 15, 2017. The App Engine flexible environment is generally available and offers features such as multi-zonal deployments, modern network stack, multiple region availability, and more. For more details, see the documentation <https://cloud.google.com/appengine/docs/flexible/> and new features to consider when upgrading <https://cloud.google.com/appengine/docs/flexible/python/upgrading#new_features_to_consider_when_upgrading> . If you have any questions or concerns specific to one of your projects, please use this form to contact Google Cloud Support <https://support.google.com/cloud/contact/gae_managed_vm_turndown>.
