Interesting that the differential between different regions is remaining the same.

You would imagine that if some big user were slurping up all the spot instances worldwide, then it would level out regional pricing differences. Or, if not level it out, change it based on that users sensitivity to bandwidth costs in/out of each region.

That makes me think that the spot pricing change is a gradual AWS algorithm change instead - I'm sure they'd be smart enough to apply a pricing change with some smooth function based on date.

You can shop around a bit for AWS for spot instances. Spot prices in eu-west-3 (Paris) are not that wild yet for the same c5a instances. Somteimes, a region has all its spot instances near the on-demand price. At least they seem to be smoothing out their changes over days. (I think it used to be more wild in the past.)

That happens? I’ve pretty consistently had all spot prices at 30-40% of on-demand.

The problem is there's been growing demand across the world and/or more people optimizing costs and moving from on-demand -> spot. It's not a single user doing this.

There were hardware shortages earlier. I think it's just a case of AWS can't expand fast enough to meet demand for now.
