WHISPER BUG IS VERY ANNOYING
Usually if there’s a delay with whispers, there’s some sort of internet/network problem. Check your ping to make sure it’s about the same as usual. If it is, then it might be that the route from your computer to the chat server is different from the route to the game servers.
Typically, if the problem is on ANet’s end, lots and lots and lots of people would experience the problem at exactly the same time; that doesn’t seem to be the case.
If you don’t feel like doing the troubleshooting work yourself (and who could blame you? you’re here to play a game), file a support ticket and someone from ANet will try to work with you to figure out the issue.

I’d have said that too, but even with a 10:1 expansion for hyperbole that’d still be a minute delay, which is gonna show up in other issues in open world content, etc, I’d think?
