This article provides an overview of the Radix registry environments hosted on Tucows Registry Services. It outlines the available Operational Test & Evaluation (OTE) and production systems, including EPP endpoints, registrar consoles, and WHOIS/RDAP services, to help configure, test, and prepare integrations ahead of the Radix transition.
New registrars to Tucows Registry Services
New registrars will receive an onboarding email from Tucows containing:
- OTE credentials
- Certificates
- System access details
Important: The onboarding link expires 30 days from the date it is sent.
New registrars must:
- Access and download the onboarding details before the link expires
- Log in to the Radix OTE environment
- Test required EPP commands
Existing Tucows registrars
If you already work with Tucows Registry Services for other TLDs:
- Your existing EPP and Registrar Console user credentials will be copied from tucowsregistry.com environment to the Radix OTE and production environments
- Use your existing EPP client certificates to connect to the RADIX EPP servers (OT&E and Production environments use different certificates)
Production environments are not live yet. Tucows will notify registrars when production access is available when transition is complete.
Registrar Action: OTE Onboarding and Testing
To support a smooth transition, registrars are strongly encouraged to onboard and test in the Radix OTE (Operational Test & Evaluation) environment ahead of transition.
Testing is critical to ensure your systems are fully compatible with Tucows Registry Services before production go-live, especially if you do not currently manage other TLDs on the Tucows platform.
Registrars who do not complete onboarding and testing may experience:
- Connection issues post-transition
- Delays in domain operations
- Increased support requirements during go-live
