How are customers notified if Retool outbound IP addresses change?

Hi Retool team,

We are using Retool Cloud and rely on Retool’s outbound IP addresses for allowlisting access to internal resources / databases.

I reviewed the outbound region documentation, but I want to clarify the operational side in case those IP addresses ever change.

Could you clarify the following?

  1. If outbound IP addresses change for a region, are customers directly notified?
  2. If yes, how is that notification sent (email, forum announcement, changelog, status page, in-product notice, etc.)?
  3. Is advance notice typically provided before the change takes effect?
  4. If there is no guaranteed direct notification, what is the recommended best practice for customers who need to keep allowlists up to date?

Thanks in advance.
