to overcome the bad connection in Namibia, we began compressing the raw data before uploading it.
This means, however, that you will need 7Zip for the foreseable future to work with the data.
Please download it here: https://www.7-zip.org/download.html
The archives are split in 2MB big chunks, to decompress you will have to download them all and extract them. I will work on a way to automate this, but it will take a little while to do it safely.
