ACTION REQUIRED: Upcoming certificate expiry for two-way TLS for tsysssl.arcot.com

The maintenance is now complete. Thanks for your patience.

The scheduled maintenance is now underway. We'll keep you updated on our progress.

The tsysssl.arcot.com URL certificate expires on 9 May 2023. To ensure the continued operation of secure API connection using two-way TLS certificate the following steps must be completed to trust the new certificate. These steps must be completed by 28 Apr 2023 to ensure service continuity after Arcot installs the renewed certificate at 0500 GMT on 03 May 2023. The root and intermediate remain unchanged and only a new leaf certificate has been issued. If you already have the root and/or intermediate trusted then there is no action required.

To obtain the certificates, follow the link to our knowledge base https://knowledge.broadcom.com/external/article?articleId=250093 and download the file listed 1663254903998__tsysssl_arcot_com_219605874.zip.

Arcot’s recommendation is to trust the Root and Intermediate certificates. If you are required to also trust the Leaf certificate, please ensure that all three certificates are loaded into your Trust Store. To avoid impact to service, the existing certificates must not be removed until they have expired.

As an acknowledgement, please inform Broadcom CSM/PM or raise a support case that: You have received the renewed certificates properly (as sometimes they are corrupted) The action required at your end with an ETA so we can line up downstream plans accordingly

Once you have installed the new certificates, Arcot can verify connectivity before switching production traffic to use the new certificates. Arcot will also monitor the transactions post switching of the production traffic and notify if required.

If you have any questions, kindly create a case through the Broadcom Support Portal (https://support.broadcom.com/) .

Sincerely, Arcot Support Team
