IMPORTANT : Authorize Net TLS 1.0 and 1.1 Temporary Disablement Schedule
For merchants that are using Authorize Net to take payments, recently you should get an email from Authorize Net about a temporary disablement schedule for TLS 1.0 and 1.1.
Authorize Net will temporarily disable those connections for a few hours on January 30, 2018 and then again on February 8, 2018.
Merchants using TLS 1.2 by these dates will not be affected by the temporary disablement.
We strongly recommend that connections still using TLS 1.0 or TLS 1.1 be updated as soon as possible to the stronger TLS 1.2 protocol.
We already have a previous blog post about this important update earlier:
And for your note, the deadline for permanent disablement for TLS 1.0 and TLS 1.1 is on February 28, 2018.
