Right now the option you’d usually use for 10G to the internet doesn’t say it supports RX-line servers.

If you search for “10G dedicated uplink” and look in the rightmost column it covers what they will support requests on.

I’ve successfully used it on AX and SX many times and I’d be happy to see Hetzner also support RX!

I'd also probably order the 10G for that price if it was just a checkbox in the order process. But opening a ticket later (and downtime for the server), or waiting substantially longer for the server to be available isn't really an option for me. I'm wondering if they deliberately do that because their switches couldn't handle too many 10G servers?
