Geographical spread of the data

But that is what I am saying. If the algorithm favors the fastest nodes only without considering additional requirements, then maybe the algorithm needs reshaping.
I give you additional ideas what the algorithm should consider:

  1. Storage only in a specific region (like GDPR requires)
  2. Storage in n-number of redundancy region (Example: If Europe goes down have enough pieces in Asia/Pacific region to be able to rebuild the file)
  3. Location of uploader <> location of downloader. For high speed collaboration of files geographical evenly spreading is important, so a media professional in Hollywood can upload fast, but his production subcontractor in Australia can download fast as well.
