It seems likely to me that a recession or pandemic affects more than just the OP's business, so while that one customer is probably meaningless to AWS, the thought process that led to scaling back spending could be meaningful.

Interestingly, I had the opposite takeaway.

0.3% of monthly revenue from a single customer's reduced spending only a couple months in to a multi-year recession is pretty alarming.

Makes me wonder if OP's company is particularly exposed to retail, travel, or another sector severely impacted by the first order effects of the virus.
