Good morning,

We will be completing a maintenance update to the CDS Trader Dress Rehearsal (TDR) service on Tuesday 29th September 2026.

The service will be unavailable from 8:30am on Tuesday 29th September 2026 until 9am on Wednesday 30th September 2026.

During this maintenance window we will be refreshing the below data held in TDR:

• Where applicable, aligning the CDS TDR environment to Production CDS 5.3.0 Release (which will take place on 26th September 2026).
• Refreshing Trader personal, account, and licensing data held in CDS TDR, using data which will be copied from Production on 29th September 2026.
• Refreshing UK/EU Tariff data held in CDS TDR, using data which has been copied from Production on 9th September 2026.

*Trader Dress Rehearsal is a sandbox environment and is regularly refreshed with Trader data and data from the Online Tariff on a given date, as such any CDS changes to Trader data in the live service or updates to the Online Tariff will not be reflected in TDR instantaneously.

There will be a complete outage during this period. Please can you inform your contacts.

Kind regards,

TDR Communications Team

Notification from Descartes Pentant Customer Support
 
From Wed, 30 Sep 2026, 10:00 until midday BST
 
The Descartes Pentant application has been accessible over the internet for many years, requiring users to have a valid installed certificate on their computer.
 
Descartes are now removing that certificate requirement, and the websites will be accessible over the internet without it. This is to continue the progression towards customers being able to manage their own users and access within their teams.
 
User Coordinators on the system can already add new, reset, or remove user access within their organisations. Removing the requirement for the installed certificate means that as soon as the new account is set up, it can be used without waiting on Service Desk requests.
 
Organisations that wish to can take this a step further; Descartes offer Federated SSO Integrations, which allow a corporate account to be used across Descartes services. This offering has an initial setup fee and then an ongoing support/maintenance subscription, which can be arranged by contacting the Descartes Sales Team.
 
Customers using VPNs for access to the system will no longer require these, and they will be phased out at the end of 2026.
 
The same websites already in use will be accessible at a different address. The VPNs will not be cut off immediately. There will be a migration period for everyone to move over.
 
If there are any concerns, please contact the Descartes Service Desk with the subject "Pentant VPN Migration", and we can assist with your migration.

 
Users already accessing via the web at <SERVICE>.pentant.co.uk addresses will no longer be asked for certificates on logon that expire and require renewal.
 
The Pentant application will continue to have regular security scans in place to ensure the security of the service is monitored and maintained as new attack patterns and exploits are discovered across the internet.
 
Any questions, please contact servicedesk@descartes.com  
 
Please reference CHN-67838.
 
Many thanks
Pentant Customer Support Team
