One line per price movement: when AWS made the same percentage change to many prices in one publication (often the same item in many regions), it is one line with the count and one example. Only like-for-like changes are ranked: same unit, both prices above $0, and within 11x either way. The 28 changes that are not (unit changes, $0 prices, corrected placeholder prices) are left out of these lists. Large percentages often come from a very small old price. Read the description and both prices before drawing a conclusion.

Did any of these hit your bill? Drop a billing export into CostPulse Bill X-Ray: it lists the AWS list-price changes, from the same price history, that touch the usage types you pay for, and which of your cost spikes were usage, your rate or an AWS list price. Free, no signup, and the file never leaves your browser.
