"openSUSE:Leap:15.3/standard" is no longer a valid OBS repo

Hello, The Leap 15.3 OBS repo is no longer valid to pull images from.
If one tries to go to the standard repo, they’ll get a message saying “Please inform the author of the referring page that the link is outdated.”, This isn’t helpful however, as the Leap 15.3 project page has no authors listed.

Who do I inform about this? Is it intentional? is there a new project that I should use instead?
