TL;DR: We'll eventually starting enforcing a quota to curb abuse (e.g. people creating repositories full of empty commits taking up more than a GB), nothing drastic will happen immediately, and you will be able to request more space if you do need it.
Don't panic, everything will be fine!
(Feel free to ask us questions if you have any.)
@Codeberg There's a repository to which several MB of video were accidentally committed and pushed. The broken commits have since been rebased away, but the storage isn't going down. Does that mean that there are still references to it in the repository – and if so, is there a way to delete them?
