In the worst case scenario, fedia.io will be around for at least 5 more years (that is apparently the standard subset timeline). I have many more domain names if the worst comes, but there is a lot of expectation that the .io may somehow be saved due to the incredible amount of infrastructure built around it (GitHub.io, dockerhub.io, and of course fedia.io among many others)
