Host AMI running outdated code?

Hi, I’ve been running a private ec2 instance for a few months. Sometime within the last day or two, when rebooting my host instance, it started running old source code. For example, looking at my file:

This results in my test agents returning “The test completed but there were no successful results” and my /install page shows “No test agents are configured to render video”.

I’m curious why this may be occurring and why the latest code doesn’t seem to be getting pulled onto my server.

AMI ID: webpagetest-server-2014-11-25 (ami-d7bde6e7)

I’ve solved this! It turns out I was making file changes in the EC2 user data which was causing the git pull cron to fail because of unstaged file changes.
