Well, I helped start the project. And since I believe in the value
of pool.ntp.org over a single point of failure, I would much more
appreciate if Ubuntu would dedicate manpower to the timekeepers team
(that's the pool.ntp.org team) rather than to operate an NTP server
of your own.

I am aware that we had quite a number of low-quality servers in the
pool, but we are working on it. Right now, my random set here via
telekom.at's DNS servers returns:

$ /usr/sbin/ntpdate -q pool.ntp.org
server, stratum 2, offset 16.068207, delay 0.35143
server, stratum 2, offset 16.072174, delay 0.15179
server, stratum 2, offset 16.066813, delay 0.47951
server, stratum 2, offset 16.074239, delay 0.49719
server, stratum 1, offset 16.072479, delay 0.16145
server, stratum 2, offset 16.060687, delay 0.18542
server, stratum 2, offset 16.076603, delay 0.15131
server, stratum 2, offset 16.067688, delay 0.14949
server, stratum 2, offset 16.067923, delay 0.33177
server, stratum 2, offset 16.069931, delay 0.18468
server, stratum 2, offset 16.075215, delay 0.15552
server, stratum 1, offset 16.098200, delay 0.14848

Compare that to ntp.ubuntu.com:

server, stratum 2, offset 16.074332, delay 0.15231

As you can see, we are really working on the problems you guys were
experiencing some while ago with pool.ntp.org. Actually, I am
surprised to see no stratum 3 servers in the set. There are still
some stratum 3 and stratum 4 machines in there, but with the current
server count, I expect we can get rid of those soon.

But if one does install ntp-server, I bet the same resource is used
without further ado. But I have not verified that.

Please do not send copies of list mail to me; I read the list!
