Tell HN: Even HN is getting heavy traffic by AI crawlers

For about half an hour I wasn't able to access HN, and then there was a message about network traffics and HN is now prioritising human logged in users. First time I have seen this. I had to reread the sentence because in the past when server was getting heavy traffic the general advice was to log out. Now it is the other way around. I wonder what sort of traffic is HN receiving now under AI crawlers. And if other have also seen the new message.
