Unsure if this is related but I'm seeing some of the same signals. I just noticed DeadlineExceedErrors being thrown intermittently. My errors / second starting spiking about 24 hours ago which suggests that this problem has been going on for that long. Additionally I'm seeing the following message in my logs:
Request was aborted after waiting too long to attempt to service your request. This may happen sporadically when the App Engine serving cluster is under unexpectedly high or uneven load. If you see this message frequently, please contact the App Engine team. > > - Klaas Pieter -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
