Dear Sirs, on November 15, 2017 at 0:00 to 4:00 AM (the timing will be in the zone CET - Central European Time) the domain management system shutdown will be carried out. The system will be unavailable during 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. During the shutdown there will be deployed - the refractory EPP code (especially methods for poll messages and work with credit - all without changes to the existing interface, changes occur only at element texting <reason> in EPP answers) - mailing address administration options via EPP (will result in the change of schema, that is why we will launch it at the beginning of 2018, the mailing address administration options will be turned on in the next few days on the test environment, we will give you details so you can tune your systems.) - adjustments in contacts merging (we will launch it in the next weeks) - and other minor changes All these changes are already implemented on the cz-test instance. In case of any questions do not hesitate to contact me. We apologize for any inconvenience caused. Markéta Kušičková -- Markéta Kušičková CZ.NIC, z.s.p.o.
