More likely millions per hour. But even then it's not like all those sales will be lost. Most people will probably just come back later to make their purchase.
I d be interested to know the numbers - with the amount of impulse buys or marketing driven links, there s probably a lot of ads being paid for that redirect to nothing a user might just give up on
I think peak Christmas time shopping was a couple million per hour back in 2006.
I know we used to contrast that to million per minute (or second) kinds of outages that NYC financial firms could have (along with the SEC escorting you out in handcuffs if you really screwed up).
