Hi Torti. Thank you for your greeting from Germany. Yes, all of our trading partners are located in and use servers in the US. We are unable to ship huge products outside of US. I ask the same question you did - how could this happen when we are blocking? I wondered if I was missing something. When I look at the HTTP Request details, it appears that the user was trying to inject script into forms on out site. Yes, they were blocked, but our site actually went down at that time, so it seems that the the attack caused the site to go down. So, we stopped and restarted TomCat, and the problem was resolved. Maybe there is no connection, but it seems quite possible. - boneyardDec 17, 2013

you say: "Yes, they were blocked, but our site actually went down at that time, so it seems that the the attack caused the site to go down." i would focus on that, is there any logging on the tomcat that shows which IPs reached it?
