[nznog] Denial of Service Attacks

Has anyone noticed a surge in DDOS attacks from Asia? One of the Windoze servers I look after has been getting rather nailed these past few days. Most appear to be coming from Japan - at least 5 a day and every time within a few minutes of each other, lasting a minute or two. If I am really lucky, I'll get 20 in one day ... somebody loves me :-)
