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.

• Yes, I understand. I could break my organization's website cookies and cause other issues, and the rollback timing is acceptable. Proceed anyways.

Reason for PSL Inclusion

We provide each customer with their own dedicated subdomain (e.g., redhorse.spndl.link, krew.spndl.link) for branded short links and deep linking. PSL inclusion is needed for proper domain isolation between these customer subdomains.

Specifically:

• Cookie Security: Without PSL inclusion, cookies set on one customer's subdomain could potentially be read by another customer's subdomain.
• Credential Isolation: Password managers and Apple Keychain should treat each customer subdomain as a separate site, not group all credentials under spndl.link.
• Universal Links: Proper origin separation ensures Apple's Associated Domains and Universal Links work correctly per customer.

The domain spndl.link has more than two years remaining on registration and we commit to maintaining the _psl TXT record.

Number of users this request is being made to serve: ~50 customers currently, scaling to thousands. We are requesting inclusion proactively to establish proper security boundaries before scale, as retrofitting credential and cookie
isolation after users are affected would be significantly more disruptive.
