Noen jobber knallhard med å angripe www.riksavisen.no
Forrige uke tok de hovedsiten, denne gang prøvde de på mirror siten.
Vi må ha skrevet noe fornuftig, siden slike angrep blir oss til del.
Heldigvis er dette selskap vi leier server med der, istand til å slå tilbake slike angrep ser det ut til.
«The most dangerous man, to any government, is the man who is able to think things out for himself… Almost inevitably, he comes to the conclusion that the government he lives under is dishonest, insane and intolerable.»
«Am I therefore become your enemy, because I tell you the truth? »
Gal 4:16 KJV
Yesterday between the hours of 4:00 PM EST and 6:30 PM EST (approximately), a dedicated server in our facility was under a heavy Distributed Denial of Service («DDoS») attack. This attack caused outages for our other customers as well.
The server was targeted with fragmented UDP traffic; the type of traffic, and pure amount, caused latency and dropped packets to our network from our upstream providers. At one point, Level3, who is one of our providers,reported 600+ Mbps of DDoS traffic directed at the customer’s server. To put things in perspective, a typical T1 is 1.5 Mbps so this was a very large attack from hundreds or even thousands of sources. It took us approximately an hour to isolate the sources and target of the attack. Initially we attempted to block the traffic on our perimeter firewalls. To mitigate the attack our network team then worked closely with our upstream providers to filter the traffic from even reaching our network. This action ultimately restored things to normal.
I personally apologize for the problems this may have caused. We are taking immediate action in order to minimize the impact if situations like this happen again.

On the Internet, a distributed denial-of-service (DDoS) attack is one in which a multitude of compromised systems attack a single target, thereby causing denial of service  for users of the targeted system. The flood of incoming messages to the target system essentially forces it to shut down, thereby denying service to the system to legitimate users.
