Shopify Login Outage Disrupts Merchants on Cyber Monday
On Cyber Monday 2025, Shopify had a major login outage that impacted merchants around the globe and basically made one of the busiest days of the year silent. The inability to log in was first reported at around 11 a.m. ET and, at around 4,000 people, the number of users affected reached its peak. Besides those who had trouble logging in, tens of thousands of people who simply tried to access the site or to checkout also had problems, and this happened in different areas.
Due to a failure in the login authentication system of Shopify, the merchants could not access their admin dashboard or point-of-sale (POS) functionality. In short, many could not process orders, handle checkouts, or manage their store activity during the critical hours of holiday shopping.
Around 2:31 p.m. ET, Shopify admitted the problem on its status page and said that the issue of authentication flow was resolved. The figure of the users affected by the problem quickly dropped to only 128 by 2:40 p.m. ET. The company said that it was a matter of close attention and that they were monitoring the situation performance for stability.
The timing could not have been worse.
In the past, Cyber Monday brought a lot of visitors to online stores and it was a time for sellers to make big profits. Typically, small and medium-sized businesses rely on this day to hit their annual sales targets. Some stores had to stop their promotions and some others had to delay the delivery of goods until they got access back.
The analysts claim that even if the interruption lasted only a couple of hours on such a shopping day, it might bring a considerable loss of money and customer trust. Business owners who are already struggling with thin profit margins will find that the disruption is a heartbreaking reminder of how much they heavily depend on the digital infrastructure.
Shopify did not specify publicly the exact amount of sales that went missing during the outage, however, it implied that the overall sales performance could still be good because of the sales momentum from Black Friday and AI-driven shopping tools.
This episode brings to light how fragile the e-commerce ecosystems are: one technical glitch has the power to impact thousands of sellers and customers at the same time. It is a clear call for major online shopping platforms to have redundancy, transparency, and be able to provide swift fixes.
