From a deal on racknerdtracker.com (so RackNerd as the name suggests).
But their panel is a bit limited. If you want a custom OS that isn’t provided, you have to open a ticket with them to get an ISO mounted. You can also boot into recovery environment, but that is outdated minimal installation of Debian 9 without working APT. I was still able to use it to install Arch Linux from bootstrap image though. I just had to decompress it on my PC, create a temporary partition for it and scp it over.

And I am again mentioning Arch. It comes naturally.
