Lu Zhou had guessed correctly.
Xiao Ai had indeed successfully uploaded the paper five minutes earlier, and the system notification had arrived at roughly the same time.
However, although the paper had been uploaded, seeing it now was probably not going to be easy.
Because in those mere five minutes...
The arXiv server had completely crashed!
Academic websites like this normally did not receive particularly high traffic, and considering operational costs and other factors, they would not set up servers with especially large capacities.
Yet now, virtually every mathematician in the world who had subscribed to updates on the Riemann Hypothesis had received notifications through the site, or even by email.
As it happened, it was nine in the morning in North America. In what seemed like an instant, mathematicians from half the world—even scholars who were not mathematicians at all, merely working in fields somewhat related to Mathematics—had rushed over to download the paper.
Before the arXiv administrators even figured out what was happening, the traffic, like a DDoS attack, had left them utterly dumbfounded.
Then, the server gloriously went down.
Almost simultaneously with arXiv's collapse, MathOverflow, the mathematics forum for professionals around the world, had been completely flooded with discussions of the topic.
[Proof of the Riemann Hypothesis?! Did you see the arXiv push notification?!]
[See my ass! The website crashed—what the hell am I supposed to see?!]
[I was lucky enough to see it, though not through the notification. I found it in my list of tracked tags... and for a moment, I even suspected I had read it wrong.]
[God, I checked the calendar! Today isn't April 1st!]
[Has anyone finished reading the paper? Come out and tell us what it actually says! Did he prove it or not?]
[This is beyond my field of research,
