Updated ciphers require changes to SSH clients and automated services
Acquia has deprecated support for certain older, less secure ciphers needed to establish secure connections to Acquia instances in the 1.86 Acquia Cloud release. Some local SSH clients and automated processes using these older ciphers will no longer be able to connect. If you are using one of these deprecated ciphers, your ability to SSH into your website may be impacted. Additionally, automated processes using SSH to connect to your website may stop working. In anticipation of this change, we are advising customers to make any necessary updates to local SSH clients and automated processes using these older ciphers as soon as possible.
