Description
Travis builds fail all the time with errors like this:

In other words, all DNS resolution suddenly fails so nothing can be downloaded.
To test the theory that this is merely a DNS problem, do we have the ability to modify /etc/hosts on the Travis build machines? If so, we could have _ci/bootstrap.sh at least add entries for packages.macports.org, packages-private.macports.org and distfiles.macports.org. That might help some builds succeed that would otherwise have failed.

It appears that this didn't help, and that the Travis outages are full network outages, not just DNS outages.

I've asked about it now here: https://travis-ci.community/t/intermittent-network-outages-on-macos-builders/9208
Replying to ryandesign:
Probably yes, we have root access to the VM.
