Pick your servers and send the order over. We'll reply with an invoice, and nothing is charged until you pay it.
Installed once at setup, free of charge, as-is with no warranty or support afterwards. Linux only.
RAID is not a backup. We'll confirm by email if your chosen layout isn't available on this server.
Paste your public key (the .pub file). Without one, we email you a random root password once, and you should change it when you first log in.
