The maintenance is now complete. Thanks for your patience.


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


The Symantec Web Security Service team is pleased to announce a new point-of-presence (POP) in Toronto, Canada. The POP is engineered to service customers in the Toronto region and is taking advantage of the new Toronto Google Cloud region. It will be available on May 18, 2022.

As a result, Symantec will decommission the current Toronto Localization Zone, GCATO1, which is hosted in the Montreal Google Cloud region. The decommission will occur on June 18, 2022.

Carefully review the information below to avoid disruption of service.

New POP GCATO2 General Availability Date: May 18, 2022

GCATO1 Decommission Date: June 18, 2022

Ingress IP Addresses (all Access Methods):

  • - NEW MAY 18, 2022 (GCATO2)
  • - TO BE RETIRED JUNE 18, 2022 (existing GCATO1 ingress IP address)

Egress IP Addresses:

  • - NEW MAY 18, 2022 (GCATO2)
  • - NEW MAY 18, 2022 (GCATO2)
  • - TO BE RETIRED JUNE 18, 2022 (existing GCATO1 egress IP range)

Required Action

Prior to the decommission date:

  • Firewall rules regulating connectivity to/from your network to WSS 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 WSS 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 WSS, 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 June 18, 2022. This change can be made after May 18, 2022.
  • 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.
