Dear Sirs, on Tuesday December 18, 2018 at 00:00 AM to 2:00 AM the domain management system will be shut down - at this time the system will be unavailable. 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, some web presentations, the EPP system, web/unix WHOIS and RDAP; displaying a list of registrars; establishing requests for authinfo, blocking and unblocking; authentication by mojeID(just in a the first minutes in the first hour of the shutdown); mojeID profile editor; interface for creating mojeID accounts and login into the domain browser will not work as well. Within the shutdown, we will perform necessary maintenance of the backend registry. There are no software changes in the plan this time, after the upgrade we do not expect any negative operating impacts. 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
