# BREAKING CHANGE - incoming traffic from env0 extended IP list

> env zero expanded its infrastructure across additional AWS regions and AZs. Update your IP allowlists to include the new addresses by December 4, 2023.

The env0 engineering team is dedicated to enhancing the system for increased stability and resilience. As part of our ongoing efforts, we have expanded our resources across more Availability Zones (AZs) and regions, ensuring rapid recovery in the event of a complete AZ or region failure.

Clients who previously allowlisted our static IP addresses should add the new IP addresses to their allow-list. You can find a comprehensive list of all the IP addresses in our [documentation](/guides/admin-guide/custom-flows#faq) and at the bottom of this message. Rest assured, the previous IP addresses will continue to be in use.

Commencing Dec. 4, 2023, the new addresses will be active, and clients can anticipate incoming traffic from any address within the provided list.

These changes may impact the [Terraform Provider](https://github.com/env0/terraform-provider-env0) associated with env0. Customers using Terraform to manage their projects may need to validate and update their Terraform configurations to align with the new IP addresses.
