The exact change
Quotes fabricated and attributed to Adrian Cantrill, Neal Davis, Stephane Maarek (2M students figure), and Jeff Barr. Unsourced re:Invent stat claiming 65% of AWS customers use 5 core services covering 60% of exam questions. Netflix Spot Instances claim vaguely stated as up to 90% savings.
De-attributed all 4 fabricated quotes (Cantrill, Davis, Maarek, Barr) to plain prose, preserving the accurate underlying technical content. Removed the unsourced 65%/60% re:Invent statistic, replaced with a general framing about the value of the five core services. Corrected the Netflix Spot Instances claim to the verified, better-documented figure: Netflix runs an internal spot market of 300,000+ CPUs for video encoding achieving approximately 92% savings, rather than the vague unsourced up to 90% framing. Removed the now-orphaned re:Invent reference-list citation.
Suggested change
De-attributed 4 fabricated quotes. Generalized 1 unsupported statistic. Corrected the Netflix Spot Instances claim to the real, verified 92% figure with accurate context (internal spot market, encoding workloads).
Why this is better
Applied fact-check fix: de-attributed fabricated instructor/executive quotes, removed unsourced statistic, corrected Netflix Spot Instances savings figure to the real documented 92% figure with accurate context.
