Event:
2025-01-14 05:00:00
Expected Duration:
2025-01-14 07:00:00
Status:
Closed
Brief Description:
On Tuesday, January 14, 2025, between 5-7:00am, CIT Network Services will move all Cornell wired networks to new DHCP server infrastructure.
User Impact:
During this window the DHCP service will be intermittently unavailable. Client devices attempting to obtain or renew DHCP leases during the times the DHCP service is unavailable will fail to obtain an IP address. Once the DHCP service is restored, client devices will be able to obtain or renew DHCP leases, as usual. DHCP lease states will be copied over to the new servers to minimize disruptions.
Services Affected:
Network
Subsites Affected:
Wi-Fi
Wired Network
Full Description:
On Tuesday, January 14th between 5:00am and 7:00am CIT Network Services will move all Cornell wired networks to new DHCP server infrastructure. This includes all networks on the Ithaca, Geneva, and NY Tech campuses, and any remote sites connected to the Cornell network. Any network that leverages Cornell IP address space is in scope with the exceptions of CIT's Managed Server service and 10-space networks in AWS and Azure.
