Not really; as they say in the post itself, "Facebook’s business is different than Amazons and the impact on their business will be different."

Amazon's core business is selling stuff to customers: additional latency might occasionally turn away a customer. In Amazon's scale, that's a million-dollar opportunity.

Even more interesting would be if you had some data to show precisely how much.
