No they have their own network
Ohh but it's based in The Netherlands?
If you look at all the seedbox companies that started their own networks look at where they host. It's always AMS-IX. Feralhosting, Bytesized, Seedboxes.cc etc. AMS-IX is where the big traffic is especially for seedboxes. If you can get 90% of your traffic through the exchange there and then just get a transit provider like HE, Arelion (Aka Twelve99 aka Telia), cogent or others to server the rest of the world you are sorted.
