Dear Sirs, starting from Tuesday November 23, 2021 at 10:00 PM to Wednesday November 24, 2021 at 02:00 AM the domain management system will be shut down - at this time the system will be temporarily unavailable. Deleting domains from November 23 will take place before the shutdown. At that time there will not be available information associated with the registry in the Intranet - credit status, list of invoices and expired domains of registrars. Furthermore,the EPP system, web/unix WHOIS and RDAP; displaying a list of registrars; establishing requests for authinfo, blocking and unblocking; mojeID profile editor; interface for creating mojeID accounts and login into the domain browser will not work as well. Within this time window, most of our websites, including the nic.cz website, will also be shut down for a short time. The CZ zone will also not be generated and published during the shutdown. The reason of the service shutdown is the upgrade of the domain management system database. 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 M +420 603 826 732
