Two pools racing with two blocks on each side. That's not entirely healthy.

Why no good?
And now there’s a third stale block. Weird. This seems very anomalous… How do you see it? 
It's fairly common and discussed in the white paper. Absolutely nothing "unhealthy" to worry about
Two block reorgs are pretty rare. Last time was in 2020. Both blocks s both sides being from the same pool could suggesy a relay problem or a selfish mining attack. Not world ending, but worth investigating.
