And I try to make it easy on the level2 servers (most distro
naintained "pool.ntp.org" site that supply the net since I have 5 or 6
machines running mostly 24/7, I've configured my router to rebroadcast
on my local, not accessable home network. So that makes this router a
level 17 server and all the rest of my boxes get time well wihin 5
milliseconds of ntp. But to the level2 servers in the typical pool, I am
just one client.
Since its a free service but they still have to pay for the bandwidth,
and electricity to run them, it makes sense to cut the bytes used if you
can.
