ITS Update: Network disruption April 10

Posted: 18:31:42, Friday, Apr 10, 2015   Expiration: 18:31:42, Monday, Apr 13, 2015  

At approximately 4:30 p.m. today the University began experiencing intermittent disruptions to its network connectivity caused by a large distributed denial of service (DDoS) attack from hosts outside of UW-Platteville.

In a denial of service attack, the network is flooded with useless traffic designed to overwhelm the network and cause it to stop functioning normally.

Today’s DDoS attack created a significant amount of traffic which overwhelmed some of our campus network services.  ITS worked with UW-SysNet to block the unwanted traffic.  The attack was stopped by 5:15 p.m. . No data has been lost or compromised.

ITS staff work proactively to keep systems online and functioning properly.  In addition, ITS has systems in place to protect and monitor network traffic and alert staff when abnormalities occur.

It is important to note that these events are very common.  Other System schools have reported similar attacks this week.  Also, multiple attacks can come in a short period of time; we should not be surprised to see similar events occur again.

We will continue to monitor this situation and look for ways to reduce the impact of these attacks on our University community.

If you experience problems accessing the network, please contact the ITS Help Desk at 608.342.1400 or helpdesk@uwplatt.edu.
