I haven't looked at this on my auth servers but I have done some tuning on
my recursive servers related to DNS-over-TLS support for Android clients.
So I wonder if Google have implemented EDNS TCP keepalive. If you change
what BIND calls tcp-advertised-timeout, do Google's TCP connection
lifetimes change to match?

Trafalgar: Northerly 4 or 5, occasionally 6 in east. Rough, occasionally
moderate at first. Fair. Good.
