[Reg-zahr] notification of shutdown - March 22, 2021

Dear Sirs, on Monday March 22, 2021 at 10:00 PM to 11:00 PM the domain management system will be shut down - at this time the system will be temporarily unavailable. At that time, the EPP connection will not be available. Furthermore, information associated with the registry in the Intranet - credit status, list of invoices and expired domains of registrars - will not work as well. Within the shutdown we make the necessary changes to the registry infrastructure that will not have any negative impacts on its functionality. In connection with the mentioned changes in the infrastructure, since April 12, 2021, for communication via EPP we will require the following: (most of you already use the EPP this way) - encryption with TLS v1.2 or higher (TLS v1.0 or TLS v1.1 will no longer be enabled) - use of certificate with an RSA key with a length of at least 2048bit and with the SHA-256 algorithm We apologize for any inconvenience caused. Thank you and kind regards Markéta Kušičková -- Markéta Kušičková CZ.NIC, z.s.p.o. Milešovská 5 130 00 Praha 3 T +420 222 745 125 M +420 603 826 732 Většina z Vás takto již k EPP přistupuje, ostatním se ozveme.
