Dear Sirs, on Thursday August 8, 2019 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; mojeID profile editor; interface for creating mojeID accounts and login into the domain browser will not work as well. Within the shutdown: 1) we introduce a notification of contact change to the designated domain registrars to which the foreign registrar's contact is established via poll messages. That means designated registrars of domains to which the contact is established will also find out about the change of contact via a poll message. The format of such a poll message is at: https://fred.nic.cz/documentation/html/EPPReference/CommandStructure/Poll/M… 2) we implement a number of other internal technological repairs and changes All these changes are already implemented on the test instance epp.demo.regtest.nic.cz and after deployment should not cause 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
