This was a great engineering blog post in that it did a good job in describing, in detail, a large overlying problem (excess intra AZ bandwidth), its impact on margin (20%) and concrete steps to measure the problem and solution. This is exactly the type of communication we should be able to use as an example of the outsize effect engineering can have on the long term value of the company -- if there's anyway that margin increase can in some way be turned into CAGR, these increased margins could double the company's valuation in 4 years (in an ideal world, of course).

Very cool.
