In a short window, the storefront has to stay fast, checkout has to keep moving, inventory has to stay accurate, and backend workflows have to finish. Many teams handle that pressure with a code freeze, then spend the week watching dashboards instead of shipping. A freeze can cut unnecessary risk, but good preparation should also give you the confidence to act when something unexpected happens. ## Start with last year’s traffic patterns Most teams start Black Friday planning with the homepage. But product pages, search, cart, checkout, promotion paths, and limited-stock drops can all become bottlenecks, depending on how customers enter the site and which campaigns are running. A better starting point is last year's traffic, or the closest comparable event you have. Look at where traffic clustered, where latency, errors, or abandonment climbed, and which routes, functions, or third-party services generated the most backend work. That keeps you from spending the week optimizing a page that was never the problem. Use [Web Analytics](https://vercel.com/docs/analytics) to identify traffic patterns, [Speed Insights](https://vercel.com/docs/speed-insights) to track real-user performance, and [Observability](https://vercel.com/docs/observability) to investigate backend behavior across routes, functions, external APIs, and logs. You can see which pages spiked, how performance shifted by route, device, browser, or region, then drill into the function, path, external API, or log behind a slow request. ## Load test the transaction path A storefront can pass a general load test and still fail on the transaction path under concurrency. A product page may load quickly and the cart may render, while the promotion engine, inventory service, or payment workflow behind checkout starts to slow down. Promo codes, cart recalculation, inventory checks, payment initiation, tax calculation, fraud checks, order creation, and confirmation all deserve their own tests, because they behave differently from static or cached pages. These are the paths where Black Friday traffic turns into real business impact, even when the rest of the storefront looks fine. [Preview Deployments](https://vercel.com/docs/deployments/environments#preview-environment-pre-production) give you a live environment to try changes before they reach production. Test a promotion update, checkout change, or inventory path against a preview URL, review it with stakeholders, and promote it only when you're confident. ## Make rollback part of the launch plan A Black Friday launch plan needs the path forward and the path back. You should know what ships, who approves it, how it's monitored, and exactly how to return to the last known good state if something breaks. Before the peak window starts, identify the last known good deployment, decide who can roll back production, agree on the metrics that trigger that call, and confirm where you'll communicate if a rollback touches multiple systems. [Vercel Instant Rollback](https://vercel.com/docs/instant-rollback) lets you revert to a previous production deployment from the dashboard. It points the domains back to the deployment you select, giving you a fast recovery path for breaking changes during high-traffic windows. ## Set monitoring thresholds before traffic arrives Define thresholds for error rate, latency, checkout completion, cart abandonment, function duration, and external API performance before traffic arrives. A good monitoring plan covers the customer experience, the transaction path, backend health, security signals, and business impact, so on-call knows when to investigate, escalate, or roll back. Vercel Observability helps you monitor performance and traffic with framework-aware insights that map to how your app is built. Drill into routes, functions, external APIs, and logs to find where a problem starts. Log Drains can also send logs to the tools your on-call team already uses, so Black Friday monitoring fits your existing workflow. ## Reduce backend pressure before it reaches checkout Black Friday planning should include the work that keeps unnecessary load off your backend. The fastest backend request is the one your app never has to make, because the content is cached, regenerated efficiently, or filtered out before it reaches the app. Review where you can cut backend load before campaigns go live. Cache high-traffic pages and assets that don't need to be regenerated on every request. Product pages, pricing, and inventory indicators may need a regeneration strategy that keeps content fresh without a full redeploy. Move non-critical work out of the checkout response path whenever possible, and review your [firewall and bot rules](https://vercel.com/docs/vercel-firewall) before peak traffic hits. During [BFCM 2025](https://vercel.com/blog/bfcm-2025), Vercel's global cache served over 56.9 billion requests, and ISR processed over 1.8 billion reads and 1.5 billion writes. Vercel also took over 7.5 billion firewall actions and blocked over 415 million bots in the same period. Those figures show why filtering matters at peak: every firewall action and blocked bot is load your application never had to process, keeping capacity free for real customers. ## Confirm on-call access before the freeze An on-call rotation only works if the people on call have access and the confidence to act. Before Black Friday, confirm who gets paged first, who can approve changes, who can roll back production, and who owns each critical part of the customer journey, from storefront and checkout to payments, inventory, search, and fulfillment. Vercel supports these workflows by making rollback, deployments, observability, and access controls part of the same platform. Decide ahead of time who can perform production actions, then give the on-call rotation the permissions they need before the window opens. ## Get ready for Black Friday with Vercel During BFCM 2025, Vercel handled more than 115.8 billion total requests, peaked at 518,027 requests per second, and supported more than 6.1 million deployments across the weekend. ## Related resources - [Billions of requests: Black Friday-Cyber Monday 2025](https://vercel.com/blog/bfcm-2025) - [Just another (Black) Friday](https://vercel.com/blog/just-another-black-friday) - [Helly Hansen migrated to Vercel and drove 80% Black Friday growth](https://vercel.com/customers/how-helly-hansen-migrated-to-vercel-and-drove-80-black-friday-growth) - [How KIKO Milano scales for Black Friday](https://vercel.com/customers/how-kiko-milano-scales-for-black-friday) - [Vercel Firewall](https://vercel.com/docs/vercel-firewall) and [Bot Management](https://vercel.com/docs/bot-management) documentation
