The short answer: vercel is reliable overall but not incident-free: StatusBird's independent monitoring recorded 99.95% availability with 1 major incident totaling 1 hour 6 minutes of downtime in the last 90 days.
Below is the data behind that answer and how Vercel compares to its peers.
What is Vercel?
Vercel is a cloud platform for hosting frontend applications, best known as the company behind Next.js. E-commerce brands use it to run headless storefronts built with Next.js or other frameworks, often on top of Shopify, BigCommerce, or commercetools backends, relying on Vercel's edge network, serverless functions, and instant deployments.

What happens to your store when Vercel goes down?
If your storefront is hosted on Vercel, a Vercel outage can take your entire site offline: customers get errors or timeouts on every page, which means zero traffic, zero conversions, and zero revenue until it recovers. Partial incidents can be subtler, with serverless or edge functions failing so pages load but cart actions, search, or API-backed features break. Deployments can also fail, blocking you from shipping fixes. Your commerce backend and its hosted checkout may remain healthy even while the Vercel-hosted frontend is dark.
Typical symptoms during a Vercel outage:
- Storefront returning 500-series errors, timeouts, or a blank page for all visitors
- Pages render but cart, search, or account features backed by serverless functions fail
- Deployments stuck in queue or failing in the Vercel dashboard
- Vercel dashboard itself slow or unreachable
- Sudden traffic and sales flatline in analytics

Frequently asked questions
My whole store is on Vercel and it is down. Is my data safe?
Yes. Vercel hosts your frontend code and functions, while your products, orders, and customers live in your commerce backend such as Shopify or your database. An availability incident does not delete anything; the store returns as soon as hosting recovers.
Can I move off Vercel quickly during an outage?
An emergency migration mid-outage is rarely practical because DNS changes, builds, and environment variables take time. The better play is a prepared fallback, such as a static maintenance page or your platform's hosted storefront, that you can switch on within minutes.
How this data is measured
StatusBird checks Vercel's status every 2 minutes, around the clock, independently of the vendor. The availability figure counts major and critical outages only; minor degradation is excluded so numbers are not skewed by vendors that report small blips near-continuously. Grades run from A+ to F. See the live numbers on the Vercel reliability page and current status on the Vercel status page, or browse all 84 service grades.
Know before your customers do
StatusBird monitors Vercel and 83 other services online stores depend on, plus your own storefront, every 2 minutes. When something goes down you get an SMS, email, or Slack alert with plain-English context, usually before the official status page catches up.
