Should I use CDN for Black Friday?

As an e-commerce business preparing for Black Friday, I'm concerned about website performance during high-traffic periods. I've heard about Content Delivery Networks (CDNs) but I'm unsure whether they're truly necessary for my online store. I want to understand the potential benefits, costs, and implementation complexity of using a CDN during peak shopping seasons like Black Friday, where every second of page load time can impact conversion rates and customer experience. What are the key considerations for deciding whether a CDN is right for my specific e-commerce needs?

TL;DR - Quick Answer

Shopify already uses a global CDN (Fastly) for all stores - your images, product pages, and static assets are automatically served from edge nodes near your customers. No additional CDN setup is needed for standard Shopify stores.

Should I Use CDN for Black Friday?

If you're on Shopify, you're already using a CDN - Shopify serves all storefronts through Fastly's global edge network. Your images, stylesheets, scripts, and pages load from servers geographically close to your customers automatically. There's no CDN to "enable" for a standard Shopify store.

What Shopify CDN Covers

  • - Product images and gallery assets
  • - Theme CSS and JavaScript files
  • - Storefront HTML pages (with caching)
  • - Files uploaded to Shopify Files section

What Is Not CDN-Protected

  • - Real-time cart and checkout (server-rendered, not cacheable)
  • - Third-party app scripts (each app's own CDN situation)
  • - Custom API calls to external services

Action Item

Instead of worrying about CDN, focus on image optimization: compress all product images to WebP format before Black Friday. Large, uncompressed images are the most common cause of slow load times - and unlike CDN infrastructure, this is entirely in your control.
