Huh... even downloading over HE.net's tunnel doesn't kill it (within the 3 attempts I've tried) now. I have previously added a passive cooler to the USB/NIC chip as the RPi3 was down for this test.
I'll keep the RPi3 up as a caching DNS + IPv6 gateway (ie. as before, minus DHCPv4), point DNS queries to it, and see how it behaves for the next week.
