AlmaLinux-9-GenericCloud-latest.x86_64.qcow2 failing to download

[rfparedes]

I have automated process that downloads: https://repo.almalinux.org/almalinux/9/cloud/x86_64/images/AlmaLinux-9-GenericCloud-latest.x86_64.qcow2

This is failing to download in entirety. I've tried from multiple locations and servers.

The https://repo.almalinux.org/almalinux/9/cloud/x86_64/images/AlmaLinux-9-GenericCloud-9.5-20241120.x86_64.qcow2 downloads fine.

@rfparedes ,

Thanks for letting us know. I cannot reproduce the issue and working with the Infrastructure SIG to find out the root of the issue.

This is now resolved. Since the *-latest files are symlinks that point to the latest release, I believe that someone requested the file (symlink) while it wasn't finished syncing, causing it to cache a partial file with the wrong content-length, making everything go haywire. I went ahead and checked the Fastly VCL configuration and saw nothing wrong with it. I verified that the downloads worked fine when bypassing Fasly.

Purging the chained service (that handles the caching) seems to have resolved the issue (and verified the content-length was incorrect).

@codyro Thanks Cody. I can confirm also, all is good now.
