i recently signed up to heroku, which is similar to glitch except for the infrastructure- which is powered by containers called dynos, these are lightweight isolated linux containers which can be scaled up or down and fall into different catagories depending on how you plan to use the dyno.
i think that having a system like this would significantly reduce downtime and costs, while also remianing free and customisable. https://www.heroku.com/dynos
Yeah, I also think that we should be able to customise our specs a little. For example if you wanted to host a cdn you could just get storage rather than ram/cpu
