Action Required: IP Address Change for CTC Endpoints

As part of a scheduled migration, the IP addresses used by the Cloud SWG endpoint ctc.threatpulse.com will be changed. The new IP addresses will take effect on October 18, 2024 starting at 21:00 UTC. This maintenance will last for up to 24 hours.

• ctc.threatpulse.com will change to: 34.160.207.170 and 34.49.245.121
• ctc-uat.threatpulse.com will change to: 35.244.188.136 and 34.120.5.193

Note: The old IP addresses will remain functional for one week, but they will be removed from DNS responses at the conclusion of the maintenance to allow for any long-term DNS caching or CTC hard coding. After one week, the old CTC servers will be shut down.

Required Action

• To ensure continued service operability, traffic destined for the aforementioned addresses should be allowed to egress from the corporate network.
• Please update your networking and firewall rules accordingly.
• Update any private DNS resolvers as needed.
• If leveraging the CTC IPs directly, please update to the new IPs promptly.

Impact

During the maintenance no customer impact is anticipated.

Throughout the maintenance:

• Cloud SWG end-user traffic processing will continue to function.
• All end-user traffic logging will be collected and processed into reporting infrastructure.
• Agent datacenter selection services will remain functional.
• User Identity and Group membership information from SAML based authentication will remain available.

At the conclusion of the maintenance, the Cloud SWG CTC component will be hosted on new IP addresses. Firewall rules may need to be updated as described in the Required Action section above.
