Product and Features Updates


The Deactivate Autopilot feature is now available. You can now remove sites from your Autopilot-enabled list and ensure Autopilot is not used on sites that are incompatible.

Log Files on Pantheon - Log files track and record your site's activity to help you find, debug, and isolate current or potential problems on your site. Each environment has individual log files which can be obtained using SFTP. Additionally, application-level logs can be accessed directly through Drupal.
