I created this site because I occasionally need to sync a blockchain in a hurry.
I've rented a few cheapo servers for seeding (2 in NA, 2 in EU). With it I can max out standard cable internet connections when downloading the torrent.
The next target will be the ETH blockchain, but it's currently too large to fit on the cheapo servers.
Lemme know if you have any questions or comments.
