### **Primary Data Centers and Caching Servers**

As of the latest updates, Wikipedia’s primary data center is located in **Tampa, Florida, USA**. This data center serves as the main hub for Wikipedia’s operations, housing a significant portion of its infrastructure. Additionally, there is a caching server located in the **Netherlands**, which helps reduce latency and improve access speeds for users in Europe and other parts of the world.

The Wikimedia Foundation is also working on setting up a **second primary data center in Ashburn, Virginia, USA**. This expansion is part of efforts to improve redundancy and ensure that Wikipedia remains online even in the event of unforeseen disruptions.

### **Infrastructure and Technology**

Wikipedia’s infrastructure is highly sophisticated, designed to handle the massive traffic it receives. Here are some key facts about its technical setup:

1. **Application Servers**: Wikipedia uses over **200 application servers** to handle user requests. These servers run the MediaWiki software, which powers the encyclopedia.

2. **Database Servers**: The platform relies on **20 database servers** to store and retrieve the vast amount of content. These databases are managed using MySQL, and they can range in size from 200 to 300 gigabytes.

3. **Caching Servers**: To improve performance, Wikipedia uses **70 Squid cache servers** located in different parts of the world. These servers cache frequently accessed pages, reducing the load on the main database and speeding up page loads for users.

4. **Software**: Wikipedia is built using the **MediaWiki software**, an open-source platform originally developed for the encyclopedia. MediaWiki runs on a LAMP stack (Linux, Apache, MySQL, PHP), which is a common setup for web applications.

### **Why Does Wikipedia Ask for Donations?**

Wikipedia is free for everyone to use, and it doesn’t display advertisements. This is made possible by the Wikimedia Foundation, which relies heavily on **donations** from users around the world. These donations fund the servers, maintenance, and development of the platform, ensuring that Wikipedia remains independent and accessible to all.

In recent years, the Wikimedia Foundation has also focused on building an **endowment** to secure the long-term future of Wikipedia. This endowment aims to create a financial safety net, ensuring that the encyclopedia can continue to operate even in challenging times.
