Wednesday, 10 January 23 hours and 59 minutes

The maintenance is now complete. Thanks for your patience.


The scheduled maintenance is now underway. We'll keep you updated on our progress.


We are pleased to announce that the Milan Localization Zone (GITMI1) will be upgraded to a compute point-of-presence (POP) in Milan. The new POP, GITMO1, is engineered to service customers in Italy and the surrounding region. GITMO1 uses the new Google Cloud region europe-west8 in Milan. It will be available on January 10, 2024.

Carefully review the information below to avoid disruption of service.

New POP GITMO1 General Availability Date: January 10, 2024

GITMI1, GITMI11 Decommission Date: January 31, 2024

Ingress IP Addresses (all Access Methods):

  • - NEW January 10, 2024 (GITMO1)
  • - TO BE RETIRED January 31, 2024 (existing GITMI1 ingress IP address)
  • - TO BE RETIRED January 31, 2024 (existing GITMI11 ingress IP address)

Egress IP Addresses:

  • - TO BE RETIRED January 31, 2024 (existing GITMI11 egress IP range)

Required Action

Prior to the decommission date:

  • Firewall rules regulating connectivity to/from your network to Cloud SWG should be adjusted to allow traffic to pass to the NEW IP network listed above.
  • Third party applications that regulate connections by source IP address should be updated to accept connections from the NEW egress IP networks listed above to ensure traffic proxied through Cloud SWG can reach the application.
  • Auth Connector must be able to communicate with all egress ranges listed above on TCP 443, where applicable.

Failure to make these changes could prevent users from connecting to Cloud SWG, accessing third party web applications, or authenticating against the service using the Auth Connector (where applicable).

  • IPsec: Customers must update their tunnel configurations to point to the NEW ingress IP address before January 31, 2024. This change can be made after January 10, 2024.
  • WSS Agent, SEP Agent: Agent traffic will be automatically redirected to the new POP. No customer action is required.
  • Explicit proxy and proxy forwarding: Customers directing traffic to will be automatically redirected to the new POP. No customer action is required.
  • Regardless of the connection method, any configuration pointing to a specific POP hostname or IP address (not recommended) must be manually switched to the new POP prior to the decommissioning date to avoid an outage.
