Web Security Service Announcement São Paulo (GBRSP) Maintenance March 16, 2021

The scheduled maintenance has been completed.

Scheduled maintenance is currently in progress. We will provide updates as necessary.

The São Paulo (GBRSP) WSS site will undergo maintenance beginning on March 16, 2021 at 03:00 UTC lasting for a duration of up to 36 hours.

• Expect the site to be completely unavailable for 12 hours starting on March 17, 03:00 UTC, during the maintenance window. • No IP address changes will occur with this maintenance. • Carefully review the information below to avoid disruption of service.

Ingress IP Addresses The IP addresses you forward traffic to for filtering. The IP address must match the connection method. For example, do not connect IPsec tunnels to the IP address for WSS Agent.

IPsec / Proxy-forwarding / Explicit / SEP Agent (Explicit Mode):

• 34.95.130.164 - NO CHANGE

WSS Agent / Unified Agent:

• 34.95.146.164 - NO CHANGE • 34.95.225.164 - CAN BE RETIRED AFTER THE MAINTENANCE

Egress IP Ranges The IP addresses WSS will use to access content on your behalf and to deliver filtered content to your users. If you use application or firewall access control lists, add new IP ranges prior to the maintenance:

• 34.95.130.0/24 - NO CHANGE • 34.95.146.0/24 - NO CHANGE • 34.95.225.0/24 - NO CHANGE

Impact Expect the site to be completely unavailable for 12 hours starting on March 17, 03:00 UTC.

Required Action by Connection Method • IPsec: Switch to your secondary tunnel prior to the maintenance window. • WSS Agent and Unified Agent: User traffic will be automatically redirected by the service to the nearest alternate site during the maintenance window. • SEP Agent: User traffic will be automatically redirected by the service to the nearest alternate site during the maintenance window. • Explicit proxy and proxy forwarding: Customers directing traffic to proxy.threatpulse.net will be automatically redirected by the service to the nearest alternate site during the maintenance window.

WARNING: Any customer, regardless of connection method, with a configuration pointing to a specific site or IP address must manually failover to a secondary site during the migration window to avoid an outage. Explicit redirection should never point to an IP address. Only IPsec connections should be directed to IP addresses.
