This happened to me a few minutes ago. I clicked that link, it said "no advisory", I was making the same comment you made, then tried refreshing and the advisory came back.
Insane. It looks like they are showing no advisory on first page view, then advisory? Can others confirm?
I only see “no advisory” at the OP link. Refreshed 4 times with gaps in between.
Can confirm. It seems to be showing the advisory for me about half the time. Strange.
