This message is actually from 2017, and I would hope it does not apply to openjdk specifically, and the site is down only temporarily. If I remember right, there is commitment to OpenJDK in its various flavours for years to come.

Otherwise, here are a couple of decent options:
https://github.com/AdoptOpenJDK/openjdk-jdk8u
http://deb.debian.org/debian/pool/main/o/openjdk-8/

It seems Oracle shut down the complete java.net site...

"We're sorry the java.net site has closed.

Most Open Source projects previously hosted on java.net have been
relocated. Please contact the corresponding project administrator for
relocation information."

Does anybody know where the official repository was relocated to?

The only thing I'm aware of is the read only mirror at
https://github.com/openjdk/jdk which doesn't host the jdk8u AFAIK...
