Slight inaccuracy, the data only goes back to 1979 and has not yet been verified by NOAA which has data going back to 1880.
It’s also worth noting that this is based on the Climate Reanalyzer which is intended for forecasting temperatures, not record keeping.
It would be more accurate to say it was the hottest day ever recorded by the Climate Reanalyzer.

This. It's also not accurate to say it's the warmest we've been in the past 10,000 years, it was likely warmer during the roman warm period, and potentially a couple of other points. So we can only really say it's the warmest we've seen in the last couple hundred years.
That's not to say this isn't concerning, we're on track to smash the roman warm periods average temperatures within our lifetimes and make the earth the hottest it's been since the paleoscene, which would have massive ramifications. But we're not there yet, the problem is that we will likely get there in the next few decades.
At least the "medieval warm period" which gets cited a lot, was a regional phenomenon and global temperatures are higher today. The Wikipedia page seems to suggest the same for the Roman warm period.
The Roman warm period was about 2 degrees F warmer than today when you're measuring global average temperatures, not just in europe, although it was more pronounced in europe. At current rates though, we'll break that bar in 40 years or so though
Imma need some sources for that claim.
