Dear Sirs, on Wednesday, August 31, 2016 at 00:00 to 4:00 AM (the timing will be in the zone CEST - Central European Summer Time) a planned registration 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 loging into the domain browser will not work as well. During the shutdown there will be deployed changes in error messages that we have done after rewriting of the Registry code section (detailed information were sent on August 23, 2016) and changes associated with the planned transfer to Ubuntu Xenial. These changes are already implemented on the cz-test instance. We apologize for any inconvenience caused. Thank you and kind regards Marketa Kusickova -- Markéta Kušičková CZ.NIC, z.s.p.o.
