A problem faced by users in a dictatorship country when using Nala Fetch #73
Description
People in a dictatorship country need to use proxy to access foreign networks, so their IP addresses often change.This resulted in the fastest image source selected by Nala Fetch becoming almost unavailable after the proxy node changed. It is hoped that a flag can be provided to always choose the globally available image source, such as deb.debian.org / mirrors.ubuntu.com.They are automatically redirected to the nearest available mirror based on the region.
