Dear Sirs, due to the error detection in OpenSSL libraries (specifically the implementation of TLS Heartbeat) we will perform today, on April 9, 2014 at 11:00 PM an upgrade of openssl library and a certificate replacement. This action will be associated with EPP restart, so your connections will fail at that time. You can find a new certificate in the attachment. Sorry for any inconvenience caused. More information about the error can be found here: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0160 Thank you and Kind Regards Marketa Kusickova -- Markéta Kušičková CZ.NIC, z.s.p.o.
