Biggest increases

No increases to list.

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 4 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.
