Scheduled

Monday July 28th, beginning at 7:00 AM, the public user networks in EC2 will be deprecated and clients will be moved to a private network, with NAT for internet access.

Workstations may need to be rebooted or have their IP addresses manually refreshed after the change is complete. They should be set to automatically obtain their IP addresses from DHCP.

Existing DHCP reservations will be re-created in the new network, with the same name and a new IP. Workstations using the dynamic pool will automatically obtain a new address once rebooted.

VLAN IDs in scope are:

420
422
423
425
