What is a Denial of Service (DoS)?

A DoS is a malicious attempt to prevent the normal operation of a computer system. You may frequently see the terms 'DDoS' (Distributed Denial of Service) and 'DoS' used interchangeably, but there are some subtle differences.

If the server ntp.ubuntu.org should be temporarily unavailable, simply use another ntp server from ntp.org.
Check the panel on the right hand side here for your region in the world: http://www.pool.ntp.org/en/
Click that region and select an appropriate server.
Examples:
sudo ntpdate us.pool.ntp.org (USA)
sudo ntpdate ca.pool.ntp.org (Canada)
sudo ntpdate au.pool.ntp.org (Australia)
etc.

If you are behind a proxy, ntp will not work.
Try the workaround specified here: http://kubuntuforums.net/forums/index.php?topic=3102082.msg172306#msg172306

It doesn't appear to be a DNS issue; it rather appears to be a known bug with "ntpdate-debian".
After reading this: http://help.lockergnome.com/linux/Bug-515702-ntpdate-servers-default-configuration--ftopict492739.html
I'd say your options are to a) either edit the ntpdate-debian script and set NTPDATE_USE_NTP_CONF=yes to NTPDATE_USE_NTP_CONF=no, or b) to simply rename the /etc/ntp.conf file to /etc/ntp.conf.bad.

Then run
ntpdate-debian
again and see if it works.
