One of Amazon.com Inc.’s busiest sales day of the year, Prime Day, came with a few technical hiccups that began about 9 p.m. Eastern on Monday, according to digital performance analytics company Catchpoint Systems Inc.
Prime Day, a 30-hour sale that runs through midnight Pacific tonight, offers discounts and specials on hundreds of products to members of Amazon’s Prime loyalty program.
From about 9:10 p.m. to 10 p.m. Eastern, Amazon’s website had a slowdown, but it soon returned to normal operating speeds, says Catchpoint CEO Mehdi Daoudi.
“The slowdown was due to a resource on the home page that took a long time to load, and it caused slowdowns for some other pages, including search request, product details, add to cart and checkout,” Daoudi says.
The external resource that caused the slowdown was a tracking tag on the site, according to Catchpoint.
For example, consumers reported receiving a message in the Amazon app that “add to cart” failed. In some cases, shoppers received multiple “Prime Savings” discounts to further reduce the price of the product. Amazon could not be reached immediately for comment on the slowdowns.
Overall, Amazon’s web performance has not had any significant slowdowns as Prime Day shifted into Tuesday, according to Catchpoint data. Between 9 p.m. Monday through 8 a.m. Tuesday, Amazon.com’s home page loaded on average in 2.28 seconds, which is 2% faster than its average load time last week between July 3-9.
Issues with products not loading into carts for app users seemed to persist Tuesday.

Amazon.com’s mobile home page is loading on average in 1.28 seconds, which is 3% slower than its average load time last week, according to Catchpoint.
“As usual, Amazon is handling the extra load very well, despite the fact that their web pages got heavier than usual with all the Prime Day product images,” Daoudi says.
