TLS v1.0 and v1.1 shutdown status
Incident Report for Smarty
Following the plan for permanently retiring support for TLSv1.0 and v1.1 we have concluded our initial temporary shutoff which began on Tuesday, January 21, 2020 at 11:00am until and through Wednesday, January 22 at 4:00pm.

As of January 22, 2020 at 4:00pm all systems are now running in full-compatibility mode, meaning that they are accepting TLSv1.0 and above.

The next step in retiring support for TLSv1.0 will begin on Tuesday, February 4, 2020 at 9:30am and will concluded at 11:30am the same day wherein any requests utilizing TLSv1.0 or TLSv1.1 will be rejected.

NOTE: All times are Mountain Time (MST) unless otherwise indicated.

NOTE: Our clients who are having the greatest difficulty are running Windows Server 2012r2 (or earlier) along with .Net 4.0 (or earlier). This Microsoft article (suggesting .Net 4.7) has been helpful for many:
