[afnog] Four Years Tracking Unrevealed Topological Changes in the African Interdomain

[Honest Ornella GANKPA]

Hi Barrack,

I can open the link just fine. You will be redirected to a website with an
abstract of the book. At the very top you have the download link which
allows you to download the study in PDF

Best regards
