Amazon Prime Day is over, and what a ride it was this year. Widespread technical glitches in the first hours of Amazon’s massive annual Prime Day promotion cost the e-commerce giant an estimated $1.2 million a minute, according to One Click Retail founder Spencer Millerberg.

The total loss is difficult to nail down, in part because the exact span of the outage varied. But the data analytics firm says the outage, which included a broken landing page and links that sent potential customers to an error page, appeared to be concentrated on the East and West coasts of the U.S. for about 75 minutes. That puts Amazon’s loss in sales at about $90 million, an estimate One Click Retail based on 1P sales from 2017.
