Why at least 4 sources ? For redundancy or other reasons ?
My clients must not to talk to outside world.
3 is the minimum for a voting plurality when not all servers agree (i.e.
stated time + maximum uncertainty overlaps for all of them).
If you have 4+ then you maintain 3+ when one server goes down or
temporarily loses its mind/becomes a falseticker.
