Blog post author here - you are correct, I was wrong, and the fix is rolling out now!
Glad to see you following the discussion, Jeff. Maybe you probably could address my and others' curiosity re: the exact nature of the custom Intel Xeon E5-2676 v3 CPU? I don't think Intel could justify making any serious customization even for a customer as large as Amazon, but I would be very interested to know exactly how custom it is.
Universal request to all when doing technical documentation - "MBytes/sec" and "Mbits/sec" are much clearer, and leave only the doubt as to whether you mean 2^20 or 10^6 (and, in 95% of use cases, 10^6 is the correct choice, both syntactically, as well as in what you are actually measuring - data rates are almost always in SI units)
