Bluehost Agency Hosting Data Centers Explained

When creating a website on Bluehost Agency Hosting, you will be asked to select a primary data center location. This selection helps optimize performance for your visitors by hosting your site closer to your primary audience.

While a primary data center is selected during site creation, your website is not limited to a single location. Behind the scenes, Bluehost Agency Hosting infrastructure automatically mirrors your website across multiple data centers, allowing for automatic failover in the event of an outage or infrastructure issue.

This multi-data-center architecture is a key component in delivering the 100% Uptime SLA for Agency Hosting.

Available Data Center Locations

When creating a new Cloud or Agency website, you can choose from one of four primary data center locations:

• Los Angeles, California
• Dallas, Texas
• Ashburn, Virginia
• Amsterdam, Netherlands

Your selected location becomes the website's primary data center, where the site is primarily hosted and where origin requests and cache generation occur.

Choosing a data center closer to your visitors can help reduce latency and improve response times for content that is not already being served from cache.

How the Hosting Infrastructure Works

Although you select a primary data center, your website is automatically replicated across all available data center locations.

For example, if you select Dallas as your primary data center:

Primary Location

• Dallas, Texas

Mirrored Locations

• Los Angeles, California
• Ashburn, Virginia
• Amsterdam, Netherlands

This means multiple synchronized copies of your website exist across the hosting infrastructure at all times.

Automatic Failover Protection

One of the advantages of the Cloud and Agency hosting platform is automatic failover protection.

If an issue affects your primary data center, the platform automatically routes traffic to one of the mirrored data centers that hosts a synchronized copy of your website.

This process occurs automatically and requires no action from the site owner.

Benefits

• Continuous site availability
• Protection against individual data center outages
• Built-in redundancy
• Improved reliability and resilience
• Reduced risk of downtime

Example: Normal Operation

Example: Failover State

Because the website already exists in multiple locations, traffic can be redirected quickly to an available data center.

How This Supports the 100% Uptime SLA

Many hosting environments rely on a single data center. If that facility experiences a significant outage, websites hosted there may become unavailable until service is restored.

Cloud and Agency hosting are built differently.

The platform includes multiple layers of redundancy designed to help maintain website availability, including:

• Multiple geographically distributed data centers
• Continuous website replication
• Automatic failover capability
• Global traffic routing
• Cloud CDN edge caching

Since your website is mirrored across all available data centers, it is not dependent on a single physical location remaining online.

This multi-layer approach is a major reason Cloud and Agency hosting can support a 100% Uptime SLA.

How the Cloud CDN Fits Into the Architecture

The primary data center and the Cloud CDN serve different purposes.

Primary Data Center

The primary data center is responsible for:

• Origin website hosting
• Processing uncached requests
• Generating cache content
• Serving as the primary website location

Cloud CDN

The Cloud CDN provides:

• Global edge caching
• Faster content delivery worldwide
• Reduced latency
• Improved visitor experience

The CDN helps improve performance, while the distributed data center infrastructure helps ensure reliability and uptime.

Can I Change My Data Center Later?

There is currently no direct option to change a website's primary data center after it has been created.

However, it is possible to effectively move your website to a different primary data center using the staging workflow.

To Move a Site to a Different Data Center

1. Create a staging site in the desired data center.
2. Verify the staging site is functioning as expected.
3. Promote the staging site to production.

Once promoted, the new production site will use the data center selected when the staging environment was created.

Summary

Selecting the right data center helps optimize website performance by placing your site closer to your primary audience. Cloud and Agency Hosting automatically replicate your website across four geographically distributed data centers in Los Angeles, Dallas, Ashburn, and Amsterdam. Combined with Cloud CDN edge caching and automatic failover technology, this redundant infrastructure helps maintain website availability and supports the reliability standards behind the 100% Uptime SLA.
