rsc.io is just about the most trivial App Engine server ever. Except for App Engine taking it down for being too old a Go version, it's never had any appreciable downtime. It's possible that App Engine really is hanging up on the connection, but it seems equally possible that the VM is hanging up on the connection. I wonder if we should respond to ECONNRESET by trying one more time?

It's curious that this failure mode happens so much for frequently for rsc.io than for other services (like gopkg.in, golang.org/x, or vcs-test.golang.org).

Scanning the failures over the last year:

To me that suggests a problem specific to the App Engine service — perhaps either a bug in the App Engine version of the Go runtime, or flakiness in some network infrastructure sitting it front of the service.
