This looks good to me, r=me when ready. |

Do we know which DNS servers Travis was using before? |

@pietroalbini 169.254.169.254, which according to https://stackoverflow.com/a/32723910 is the same as the Google Public DNS for external domains, but I'm not sure if Travis has done some additional configuration in between. |
|
Hmm, if that points to the same resolver it shouldn't make a difference using 8.8.8.8, but whatever, this change won't hurt, let's try it. |
|
Yeah that's also why I've included 1.1.1.1 as backup. Though if 8.8.8.8 really responded "cannot resolve" then the OS won't consult the remaining items. |

…-Simulacrum Tries to address the recent network issues 1. Set the DNS server to 8.8.8.8/8.8.4.4/1.1.1.1/1.0.0.1 to workaround the daily "Cannot resolve host" error these two weeks. 2. Remove the unnecessary command `gem update --system` (originally added as experiment of the "Could not find a valid gem" error, which turns out to be useless).

Remove Travis shutdown debug scripts, and remove CI-specific DNS settings Since the cause of the host shutdown (travis-ci/travis-ci#4924) is found, we could revert the shutdown debug attempts to shorten the logs. Additionally, we're pretty sure a custom DNS (added in will not help travis-ci/travis-ci#9696, so reverting that part of rust-lang#51420 to reduce CI-specific settings.
