We're observing that http requests to non-https endpoints from nodes at CHI@UC to the internet are being dropped, and are working with our upstream network provider to investigate.

As a workound, you can make requests to an https endpoint, if available.

The most common reported failures are in `apt-get update` in our ubuntu images. To work around this issue, you can replace the lines "http://nova.clouds.archive.ubuntu.com/" with "https://mirrors.kernel.org/ubuntu/" in `/etc/apt/sources.list`.

Example for ubuntu 20.04:

deb https://mirrors.kernel.org/ubuntu/ focal main restricted universe multiverse
deb https://mirrors.kernel.org/ubuntu/ focal-updates main restricted universe multiverse
deb https://mirrors.kernel.org/ubuntu/ focal-backports main restricted universe multiverse
deb https://mirrors.kernel.org/ubuntu/ focal-security main restricted universe multiverse
