I did some live experimentation with manual edits to the VCL. It is the `between_bytes_timeout`, but the situation is complex. The timeout that's failing is on the varnish frontend fetching from the varnish backend. These are fixed at 2s, but because this is all in do_stream mode, the stream delays come through directly. So, as I guessed earlier, this is all inter-related with https://phabricator.wikimedia.org/T128813. We should fix that issue first before deciding what to do about the between bytes timeout for varnish<->varnish (where it's not per-service...).
