Blockchain.info is showing a hashrate significantly higher than that: about 10.05 EH/s, not 8.4 EH/s. I'm also showing a mins between blocks at 8.46 (should be 10).
I've also heard Bitcoin Wisdom has been having problems recently.
We'll find out soon enough.

Gotcha. Will take a look.
Edit: I see the discrepancy between the hash rate and time between blocks.
Hoping they are wrong. LOL
