Yesterday, Tuesday 21 January 2020 at 11:00 (AM) Eastern Time / 09:00 (AM) Mountain Time, in accordance with announcements we have made leading up to this day, we disabled acceptance of TLSv1.0 or TLSv1.1 connections to all of our APIs.
Yesterday, Tuesday 21 January 2020 at 18:00 Eastern Time and 16:00 Mountain Time, we re-enabled acceptance of TLSv1.0 or TLSv1.1 connections to all of our APIs. We did this as a courtesy to those who are still in the process of upgrading their clients to be able to connect using TLSv1.2 or greater.
Today we will be repeating this shutdown. Clients connecting to our APIs today between 11:00 (AM) Eastern Time / 09:00 (AM) Mountain Time and 18:00 Eastern Time / 16:00 Mountain Time will be rejected if their connections are using TLSv1.0 or TLSv1.1.
An email broadcast was previously sent on this topic and all new signups since that broadcast have been notified as part of the new customer registration email message.
