I was introducing a friend to Kali, and she was having trouble installing packages, we traced the problem to fact that the mirror that was being autoselected for her, http://kali.mirror.globo.tech/kali/, has a timestamp of 30-Apr-2019 18:03 on dists/kali-rolling/Release and dists/kali-rolling/Contents-amd64.gz, as well as many of the other files. Many files are older than that, and I could not find a file newer than that. Additionally, the list of versions available in that repo support the theory that it's an out of date repo and not just a timestamp failure.

Given that this repo is priority 100 for Canada, and diagnosing the problem is non-trivial for someone not familiar with debian repo mechanics, this seems moderately high priority to at least remove it from the metalink.
