Many users have noted High Demand can equate to slower download speeds.
Others have had issues in certain countries that disallow access to SourceForge.
The ZorinGroup notified earlier that they have migrated away from Sourceforge 'to a set of independent mirror servers.'
Hopefully this will allow more access at higher speeds. By all means, please share your experiences.
I have had better speeds with the new iso servers than i ever did with sourceforge. I have not yet experienced the mirrors as if i was redirected due to traffic, i didn't notice any message. 90MB/s download is a nice change from the 20 - 30 MB/s i saw with sourceforge.
Zorin Torrent is often asked about. It may be that due to the piracy and other shenanigans we are seeing on reddit, that there are good reasons to avoid Torrent in this case. But it is worth the ZorinGroup considering the option.
