To help merchants identify if they are using one of the older TLS protocols, Authorize.Net will temporarily disable those connectionsfor a few hours on January 30, 2018 and then again on February 8, 2018.
Based on the API connection merchants are using, on either one of these two daysthe merchant will not be able to process transactions for a short period of time. This disablement will occur on one of the following dates and time:
Akamai-enabled APIconnections will occur onJanuary 30, 2018 between 9:00 AM and 1:00 PMPacific time.
All other API connections will occuron February 8, 2018 between 11:00 AM and 1:00 PMPacific time.
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.
Note: If you are not using a current version of a web browser, please take a few moments to upgrade it now. Browsers released prior to 2014 may not support TLS 1.2. You can check your browser's TLS support by visitinghttps://www.howsmyssl.com/.
