Shopify drops the baton on the most important day for its retailers with Cyber Monday glitches creating investor panic

Shopify suffered a major Cyber Monday outage, locking merchants out during peak sales and sparking a 5% drop in its share price.

What's the key learning?

  • Peak-day reliability is everything in e-commerce, and Shopify’s outage showed how fragile merchant trust can be.
  • Even short disruptions during major sales events can translate into huge revenue losses across the platform.
  • Technical failures don’t just hurt merchants, they can quickly shake investor confidence too.

Background: Shopify is the Canadian e-commerce platform founded in 2006, which now powers over 1.7 million merchants globally.

What happened: This year, Shopify hit a major snag on Cyber Monday. At 11am New York time, over 4,000 users reported outages, preventing merchants from accessing admin dashboards, point-of-sale systems, and even checkouts.

What else: The issue has since been fixed, but the timing caused Shopify’s share price to drop 5% as investors questioned its reliability on one of the most important days of the year.


What's the key learning?

💡In e-commerce, reliability isn’t just a feature... it’s the whole product. Merchants depend on platforms like Shopify to run critical sales events without interruptions.

💡Even brief outages on peak days can have massive financial impacts. Last year, Shopify merchants processed $11.5 billion USD over Black Friday and Cyber Monday. So even a few hours of downtime could cost hundreds of millions in lost sales.

💡And clearly the system failures don’t just affect merchants, they also hit Shopify's share price too.
