Many UCOP customers experienced network connectivity problems on Tuesday morning, October 7. These problems were the direct result of a "denial of service" attack on our UCOP network. In this type of attack, our network is presented with more external connection requests than it can handle, resulting in loss of service for both internal and external customers. IR&C; resolved the problem promptly and normal network service was restored by 10:30 a.m. the same morning. We apologize for any inconvenience caused by this network outage.
Please contact Michael Shannon, Manager of IR&C; Communication Services at 987-0371 or if you have any questions.
Additional Information
Denial of service attacks are an increasingly common form of computer attack. They typically target a network's firewall or a specific Web site with the goal of denying service to legitimate users. General information about denial of service attacks may be found at the following Web site:
