Cleaning up years of old screenshots and files and came across this screenshot for pust.kr (Pyongyang University of Science and Technology). The domain currently doesn’t resolve but back in 2016 when the site was in the middle of an upgrade it had this message:
We are currently upgrading our homepage.
Thank you very much for visiting the Pyongyang University of Science and Technology website.
I’m currently upgrading my homepage, so please wait a minute. I’ll see you in a better shape.
