What is happening? IST has discovered that ARP denial of service protection is being triggered at an increased rate in some buildings. The issue has been observed in East Campus 1 (EC1), EC2, EC4, EC5, and Needles Hall and appears to be isolated to Windows 10 machines. Network Services is working with other IST teams to identify the source of the anomalous behaviour.
When is this happening? Issues began on Thursday, May 17 and are ongoing.
What is the impact? Clients may experience unexpected reboots of an IP phone, or a brief loss of network connectivity on the wired network. The loss of service should last approximately three minutes or less.
