There's been a lot of people asking me if/when they will come back in stock. I've finally managed to upgrade the node to allow for more VMs (runs on a SSD now instead of the HDD, RAM has been bumped from 1.5 GiB to 4). Price is the same as before. If you're interested, you can buy one at https://kyun.host/services.
Not on the website yet, but we are moving away from Revolt (currently revolt is bridged to matrix and vice versa) after some questionable moderation (read "censorship") decisions made by the Revolt moderation team towards other communities. Revolt is open source and can be self hosted but it is not federated like Matrix is.
