Mysterious Intermittent Failures on TravisCI

[geekdave]

Every so often, this plugin fails on Travis, with no particular error:

Running "saucelabs-mocha:all" (saucelabs-mocha) task
Verifying property saucelabs-mocha.all exists in config...OK
File: [no files]
=> Connecting to Saucelabs ...
Warning: Task "saucelabs-mocha:all" failed. Use --force to continue.
Aborted due to warnings.
npm ERR! weird error 3
npm ERR! not ok code 0
The command "npm test" exited with 1.
Done. Your build exited with 1.

Here is the build URL: https://travis-ci.org/ModelN/backbone.geppetto/builds/12358997

Perhaps it was a temporary connectivity issue with SauceLabs? I'd like to run this task as a prerequisite for every pull request on my projects, if possible.

Thanks for any help or advice!
