Following on from our messages and briefing at the start of the year, DDOS attacks are continuing to occur at a greater frequency than they have in previous years. We have been working to assist affected customers when they happen. Many of the attacks make use of unauthenticated UDP based services to reflect and amplify traffic against the chosen target. Open DNS resolvers (53/udp) and increasingly CHARGEN (19/udp) are the two most abused services. It's not unusual to see attacks in the order of 10Gb/s.
