This afternoon, we experienced a DOS attack that was disruptive to our network. The attack caused a software failure on one of our core routers and we had to manually fail over to the backup management module. Additionally, this attack caused a problem with one of our name servers, Rhea. This attack likely was the cause of some wireless controller crashes today as well. We have blocked the offending attacker at the firewall. Network services are now coming back up.
