I have noticed a lot of AoS servers using Aloha. I was wondering if I could set up a server to, or is that not possible?

Aloha is a server/website, not some software (that is, all ~17 servers are physically hosted by us at one location, not by multiple people).

We’re running pyspades, so you should probably poke around to find out more about it.
Disclaimer: I know absolutely nothing about hosting servers.

If you’d like more info on how to set up a server, I’d be glad to help…
