Dear Sirs,  on Tuesday December 14, 2021 at 10:00 PM to 11:59 PM the domain management system will be shut down - at this time the system will be temporarily unavailable. Deleting domains from December 14 will take place before the shutdown. At this 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. We are deploying a new version of the system during the shutdown. This versionadds the concept of an external identity that can be linked to a registry contact. This will allow you to connect the EU eID to any contact in the .CZ registry and log in to the Domain browser and use its functions. At the same time, we are launching an upgraded version of the Domain Browser. Once more, we would like to point out the necessity to switch to the new schemes, in version 2.4.2, see: https://www.nic.cz/page/744/registracni-system/ These schemes contain the new contact states needed for the above purposes and the optional `authinfo` parameter for info_contact, which will be needed from February 15, 2022, when we change the provision of contact data. If you do not switch to the new schemes by December 14, 2021, it may not be possible in some specific cases to make changes to the contacts for which you are the designated registrar, but these contactsare also connected to EU eID. 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
