Public Suffix List (PSL) Pull Request (PR) Template

Each PSL PR needs to have a description, rationale, indication of DNS validation and syntax checking, as well as a number of acknowledgements from the submitter. This template must be included with each PR, and the submitting party MUST provide responses to all of the elements in order to be considered.

Checklist of required steps

[x] Description of Organization
[x] Robust Reason for PSL Inclusion
[ ] DNS verification via dig
[x] Run Syntax Checker (make test)
[ ] Each domain listed in the PRIVATE section has and shall maintain at least two years remaining on registration, and we shall keep the _PSL txt record in place in the respective zone(s) in the affected section

Submitter affirms the following:

[x] We are listing any third-party limits that we seek to work around in our rationale such as those between IOS 14.5+ and Facebook (see Issue #1245 as a well-documented example) MathWorks does not submit suffixes to the Public Suffix List to work around rate-limits or any third-party products or tooling.

[x] This request was not submitted with the objective of working around other third-party limits

[x] The Guidelines were carefully read and understood, and this request conforms
[x] The submission follows the guidelines on formatting and sorting

For Private section requests that are submitting entries for domains that match their organization website's primary domain, please understand that this can have impacts that may not match the desired outcome and take a long time to rollback, if at all.

To ensure that requested changes are entirely intentional, make sure that you read the affectation and propagation expectations, that you understand them, and confirm this understanding.

PR Rollbacks have lower priority, and the volunteers are unable to control when or if browsers or other parties using the PSL will refresh or update.

[x] Yes, I understand. I could break my organization's website cookies etc. and the rollback timing, etc is acceptable. Proceed.

Reason for PSL Inclusion

This proposal for amending the Public Suffix List (PSL) comes as a direct response to the evolving needs and security considerations identified by MathWorks. Our initiative focuses on enhancing the security framework for our users by incorporating distinct domains associated with MathWorks services into the PSL. The inclusion of these suffixes is anticipated to fortify the security measures for customers using our platforms, with potential benefits including:

Enhanced enforcement of the Same-Origin Policy within modern web browsers, affecting the handling of cookies and other site data
Improved representation and management of these domains in discussions and policies of the CA/Browser Forum
Support for any additional applications of the PSL that could provide security or operational advantages for multi-tenant services

Number of users this request is being made to serve: The proposed changes are expected to impact all customers of these MathWorks services, both internal and external. Specific user counts for these services are not publicly available.

DNS Verification via dig
