Every Wix site is built on Wix’s powerful, highly resilient infrastructure, which processes
more than 3.8 billion requests a day. Wix’s infrastructure currently empowers more than
200 million businesses and enterprises worldwide. And it is fully managed and maintained
by Wix, with no extra steps required by users.

This relentless reliability is crucial to the success and scalability of Wix’s users which is why it
is at the core of its platform. It’s all built-in, every site on Wix benefits from this industry leading infrastructure. Wix sites get incredible scalability, expanding the limits on how large
and fast they can grow, all out of the box. Wix anticipates your success and automatically
scales your site as you continue to scale.
And there’s no extra setups, installations, or engineering expertise required. There’s zero
maintenance on the user’s end. Wix’s top-level engineers and SRE (Site Reliability
Engineering) experts are fully-responsible for automating and monitoring this infrastructure

99.98% Uptime

In 2021, Wix maintained 99.98% uptime across all its sites. It has been a consistent effort from
Wix’s engineering team to get that number as close to perfect as possible, and this effort
pays off in the high resilience of every Wix site. Wix strives to keep this uptime through their
SLO – Service Level Objective.
Wix’s top priority is ensuring that your site remains stable, even if there’s unexpected traffic
or transaction spikes. And they achieve this by constantly monitoring and enhancing Wix’s
enterprise-grade infrastructure. So you can go viral, become an overnight success, or build
your empire at scale – Wix will handle the load.

Wix maintains full transparency on its system performance and availability by posting realtime status updates.
You’ll find the most up-to-date status information here across all products, such as:
• Site loading times
• Site editing
• Premium services
• Payments
• Multilingual tools
• Customer management tools
• Privacy data

Enterprise-grade Infrastructure

Wix is engineered in a way that far exceeds the expected infrastructure needs of a user’s
site. Sites and businesses on Wix.com are served by four data centers across 3 continents,
transferring and processing data through 20 PoPs, plus over 200 CDN nodes set up across
the globe.

With tens of thousands of servers backing you up, you can fully focus on your business
knowing Wix is investing its time and effort into the infrastructure holding you up.
This global network provides the necessary reassurance needed at an enterprise level.
Even as your business ambitions and goals grow, your sites remain stable, available, and will
scale with you.

Wix’s infrastructure is engineered to put their users’ needs first:

Scalability: Wix automatically scales your site to accommodate your needs, even in
unexpected circumstances such as going viral or landing an overnight success. There’s
no limits to where you can take your business with Wix’s powerful and fully-managed

High Resilience: In 2021, Wix maintained 99.98% uptime and currently processes more
than 3.8 billion requests daily with no strain on the infrastructure. Your site is designed
to flex and handle a huge influx of traffic and transaction spikes, with no effect on its

Built-in Backups: Even fallbacks have fallbacks. There are a few factors at play here.
Firstly, Wix has data centers and backup data centers worldwide. And, when you save
your site, you’re actually saving multiple copies across 20 points of presence which can
load your site lightning fast and act as backups for each other

Fully-managed: Wix’s expert engineers and SRE Team look after it all. The
infrastructure is monitored 24/7, has built-in automatic processes to ensure everything
runs smoothly

Best-in-class technologies: Wix uses multi-cloud hosting to hold, secure, and render
your site across the world in milliseconds. Wix users benefit from four powerful
technologies in one platform, drawing on the strength of AWS, Google Cloud, Fastly,
and Wix’s own data centers.

It’s safe to say, with Wix your site remains resilient, stays available to your visitors, and will
load lightning fast no matter how successful you become.

Automatic Disaster Recovery

Wix has built automatic disaster recovery into its infrastructure.

Wix operates across tens of thousands of servers, running at lightning-fast speeds. So even
in the case of a major global disaster, sites on Wix will be able to recover in a matter of
minutes. But Wix goes one step further – theirs monitoring systems can sometimes predict an
issue before it becomes a problem, and preemptively reroutes traffic to avoid downtime
before it happens.
This transfer of information is made possible by multiple synchronized factors. As
mentioned, the infrastructure leverages a network of over 200 CDN nodes around the
globe, as well as an additional 20 points of presence that hold cached versions of sites on
Wix. Through this network, Wix can redirect traffic across four data centers located across 3
continents and the infrastructure will automatically scale to handle the increase in traffic
By operating at this scale, Wix prevents external outages in a region from becoming a single
point of failure in the system. There are processes in place which monitor the system 24/7,
and Wix is set up to automatically redirect traffic in response to potential problems or
unusual activity, such as traffic or transaction spikes.

Multi-cloud Hosting

By using a multi-cloud hosting approach, every users’ site benefits from the unified power
of AWS, Google Cloud, Fastly, and Wix’s own data centers.

This comes with a range of benefits for your site, improving both its resilience and
performance. With multi-cloud hosting, there’s no single point of failure. On the occasion
that one provider is experiencing difficulties, Wix shifts user data and requirements to a
stable location. With a massive distribution of data centers and tens of thousands of
servers, Wix can do this shift worldwide – resulting in global coverage and support for users.
And while each hosting provider offers a full-service package, Wix cherry-picks from their
best-in-class technologies. This combination of strengths amplifies the performance of Wix’s
platform and infrastructure.
Multi-cloud hosting allows Wix to provide every site with highly-resilient global coverage, it
helps to reduce latency, and can render user data in milliseconds.

Zero User Maintenance

As part of the combined efforts between Wix’s engineers and expert SRE team, their
infrastructure is monitored and consistently enhanced to improve performance,
troubleshoot potential problems, and provide the highest-quality experience to users.
With a dedicated team responsible for maintaining everything behind the scenes, Wix users
can run their business without being concerned about upkeep on site infrastructure.
