Last night we experienced a serious outage as a result of a DOS attack
against our DNS'. This at this point seems to be the only server that
was targeted. Without going into detail, has anyone else seen similar
recent behavior?  Most of the traffic was focused on UDP ports (1440,
4470, 5680, 5883, 11575, 11777, 16836, 17000, 17667), but there were
attempts to send on 80/TCP as well.

Any information would be greatly appreciated.

Thank you
