Dear Sirs, in preparation for further shutdowns and system upgrades we are planning next week on Tuesday (September 20, 2016) to upgrade the cz-test instance. Within the upgrade we will switch to the new version of OS Ubuntu Xenial, FRED 2.27 and at the same time we will clean up the database of all current data. If this planning shutdown and upgrade is against your plans with testing or otherwise complicates your situation, especially in terms of deleting data, let us know as soon as possible so we can find a mutually acceptable solution. Thank you and kind regards Marketa Kusickova -- Markéta Kušičková CZ.NIC, z.s.p.o. Milešovská 5 130 00 Praha 3 T +420 222 745 125 M +420 603 826 732
