Dear Sirs, on Wednesday, September 29, 2021 at 10:00 AM, we will perform a restart of the app server as part of the planned SW upgrades. This restart will cause a short-term shutdown of some services, especially the EPP connection, web and unix WHOIS and RDAP, furthermore, displaying the list of registrars and creating requests for authinfo. The entire service shutdown will take place in about a minute, so we believe that it will not affect you significantly, even if we implement it on a working day during working hours. Thank you for your understanding and I apologize for any inconvenience. Kind regards Marketa Kusickova -- Markéta Kušičková CZ.NIC, z.s.p.o. Milešovská 5 130 00 Praha 3 M +420 603 826 732
