You go to the home page (https://github.com/BayesianLogic/blog), there is a travis-ci.org badge that says "build error", and if you click on it (https://travis-ci.org/BayesianLogic/blog) it will show the error. You can run the tests locally (tools/testing/integration-test.sh) to see what's going wrong.
