This page previously contained information about how to link EC2 security groups between CloudBees
and your EC2 Classic resources running in the US-EAST-1 region.
As of December 2016, DEV@cloud resources no longer use EC2 classic security groups, so this method of connectivity will
no longer work.
To allow CloudBees Jenkins Masters and build machines to access your infrastructure, you must allow access to the IP addresses listed below.
Note: this information is subject to change. We will provide notice of such changes via this page.
