Azure Spot VM 2682% price increased ?!

I'm looking to setup a Basic_A1 virtual machine and am seeing weird discrepancies with the pricing.

The standard pricing is $18.75/mo for this instance.

When I convert it to a spot instance, the price displayed drops down to $0.00416/hr (or $2.9952/mo)

However, when you check the current price in the price history, the actual current price is $0.11160/hr($80.352/mo)! In other words, the price increase by 2682.69%!

Given the pay-as-you-go for an SLA guaranteed instance is $18.75/mo, why is the price $61.602/mo higher then a better product?

Shouldn't spot instances be capped as the pay-as-you-go prices? What is going on with the pricing here?

Trying to create a VM fails, because I capped my price/hr, so I obviously don't randomly get billed a massive increase like this.

Looking at the previous prices, it was $0.00434/hr($3.1248/mo) on Jan 31st 2021, and raised to $0.1116/hr($80.352/mo) on Feb 28th 2021. That's a 2571% price increase over 28 days, which is a 91% price increase per day. This is insane for a VM that only has 1 vcpu and 1.75GiB of memory.

    @Zack

    Apologies in delayed response.

    There is a bug identified on this, as the prices cannot be more than the PAYG. Team is working on fixing this.

    Hope this helps.

    Thanks, prices going above PAYG didn't make any sense. Hopefully this didn't bankrupt many people lol.
