- Cloudflare have very good adjacency (if PCH did anycast ntp, we'd use it)
- As ntp input, it is great they don't leapsmear
- Not all their nodes do ntp, hope they succeed at scaling that up
- ntpd constrains (un-auth) ntp packets within a TLS constraint window
so there is no downside (unlike pool.ntp entries which slowly decay
but that's a story for another commit..)
ok otto
