New networking changes appears to introduce a great deal of instability to the DC/OS integration test `teamcity/dcos/test/aws/cloudformation/simple`. Currently, this test has been succeeding 77% of the time on master over the last two months. However, with the changes introduced in https://github.com/dcos/dcos/pull/1672 it looks like the test is only passing ~33% of the time. When it fails, it either fails outright or fails by running long / never completing the tests.
This needs to be investigated and resolved before we can merge.
Sergey Urbanovich it is possible to connect to these clusters while the tests are running for troubleshooting. Michael Ellenburg and other people in the #tools-infra channel can help you figure out how to debug this.
There may be other instability issues introduced on the Enterprise half of this PR which I have not investigated yet.
