Syn flood attack?
Criminal behaviour and should be reported to the police. Not that they would have a clue what to do about it. You need to set up reapers so that half open TCP connections are dropped fairly quickly. In combination with that, you could do with shifting your syn request table from your host, by storing the information in cookies and tracking connections that way instead. A lot of network equipment comes with these features built in now adays.

-------------------------------------------------------------------------------- What is a distributed denial of service attack? How a "denial of service" attack works In a typical connection, the user sends a message asking the server to authenticate it. The server returns the authentication approval to the user. The user acknowledges this approval and then is allowed onto the server. In a denial of service attack, the user sends several authentication requests to the server, filling it up. All requests have false return addresses, so the server can't find the user when it tries to send the authentication approval. The server waits, sometimes more than a minute, before closing the connection. When it does close the connection, the attacker sends a new batch of forged requests, and the process begins again--tying up the service indefinitely. How to block a "denial of service" attack One of the more common methods of blocking a "denial of service" attack is to set up a filter, or "sniffer," on a network before a stream of information reaches a site's Web servers. The filter can look for attacks by noticing patterns or identifiers contained in the information. If a pattern comes in frequently, the filter can be instructed to block messages containing that pattern, protecting the Web servers from having their lines tied up. END C. |

I believe that has made it slow at loading, although that had been improved. This though is an attack on the BNP site, timed well to coincide with the broadcast. The BNP members forum was also affected last night which is proof as that is not usually affected when the BNP site is down due to its own faults.
