The last entry currently states that
Why did a previously available module become unavailable in the mirror?
proxy.golang.org does not save all modules forever. There are a number of reasons for this, but one reason is if proxy.golang.org is not able to detect a suitable license. In this case, only a temporarily cached copy of the module will be made available, and may become unavailable if it is removed from the original source and becomes outdated.
- Clarify what "suitable" licenses are and how license detection works.
- Provide a way to easily check whether the mirrored copy is available or not.
- Link to other potential solutions for module versions proxy.golang.org cannot retain forever.
