Travis builds failing randomly with network failures

[justingrant]

Since earlier tonight, Travis builds are failing with intermittent network errors in the CI environment. Below is an excerpt from the my latest build for #6980. It's taken from here: https://travis-ci.org/facebook/create-react-app/jobs/528058161

It was working OK this afternoon. For example, https://travis-ci.org/facebook/create-react-app/builds/528010947 finished around 5:45PM PDT and its results were normal: my code causing test failures, but nothing else failing. But starting with the next build around 8PM (https://travis-ci.org/facebook/create-react-app/builds/528042386), I'm seeing intermittent network failures like the ones I showed above. Some test suites pass but most fail because they can't install their dependencies.

Known problem? Am I doing something wrong? Or is this just an outage or operations issue at Travis?

Looks like this was a temporary problem on Travis's end. Builds this morning are working fine. Closing this issue.
