Please read the information below and prepare your environment before the change date. ■ Date and time 6 October 2026 (Tue), 4:00 AM - 6:00 AM (UTC) ■ Change ・Before: GlobalSign Root R3 ・After: GlobalSign Root R46 ■ Action required GlobalSign Root R46 is included in the trusted root certificate store of major operating systems and browsers. In most cases, you do not need to do anything. However, your environment may use its own trust store. A trust store is the list of root certificates that your system trusts. If your trust store does not include Root R46, the certificate chain validation will fail. In this case, the connections to the GCC URL will produce errors. Download the Root R46 certificate from the website below. Then add the certificate to the trust store of your environment. https://support.globalsign.com/ca-certificates/globalsign-root-certificates * You can find the certificate in the section "TLS Root Certificates". * This change has no effect on the use of issued certificates or on revocation checks.
