Call of Duty servers at various locations around the globe. A brief overview

Call of Duty's servers are located in various regions worldwide to ensure low-latency gameplay and cater to players globally. These servers are managed by Activision and use a mix of dedicated data centers and cloud infrastructure to maintain reliable online connectivity.

Here’s a breakdown of key server locations for Call of Duty titles like Warzone, Modern Warfare, Black Ops Cold War, and Modern Warfare II:

1. North America

• East Coast: Virginia
• West Coast: California
• Other possible locations include Texas and Illinois (Chicago area).

2. Europe

• Germany: Frankfurt
• United Kingdom: London
• Other potential hubs: Paris (France), and Amsterdam (Netherlands).

3. Asia

• Japan: Tokyo
• Singapore
• South Korea: Seoul
• India: Mumbai

4. Australia & Oceania

• Sydney, Australia
• Other regional servers may be deployed depending on demand.

5. South America

• Brazil: São Paulo

How the Servers Work:

Call of Duty utilizes Amazon Web Services (AWS) and other cloud providers to run its game servers, which means the locations are flexible and scalable depending on player activity. The servers automatically connect you to the one closest to your location for the best ping and minimal lag.

Issues with Connectivity?

If you're experiencing lag, your connection might be routed through a distant server due to load balancing or matchmaking. Tools like PingPlotter or connection test utilities (built into some Call of Duty games) can help identify latency issues. Using a wired internet connection and ensuring your NAT type is open can improve your online gaming experience.

Improving your server connectivity for Call of Duty 

Below are practical steps you can take to optimize your connection:

1. Optimize Your Internet Connection

• Switch to Wired Ethernet: Use an Ethernet cable instead of Wi-Fi. Wired connections are more stable and have lower latency than wireless networks.
• Upgrade Your Internet Speed: If your speed is low (less than 10 Mbps), consider upgrading your plan. For gaming, speeds of 25 Mbps or higher are ideal.
• Reduce Network Traffic: Disconnect other devices from your network, or limit their activity (e.g., streaming or downloading). This ensures more bandwidth is available for gaming.
• Use a 5GHz Wi-Fi Band: If you must use Wi-Fi, connect to a 5GHz band (if your router supports it). This band is less crowded and faster than 2.4GHz.

2. Choose the Best Call of Duty Server

• Use the Server Closest to You: Call of Duty automatically connects to the nearest server, but if you’re being routed elsewhere, your ping can increase.
  • Use a VPN (like ExpressVPN or NordVPN) to "trick" the game into connecting you to a closer or less congested server.
  • Turn off VPNs if they're causing a slower connection.
• Check Server Status: Sometimes, high lag is due to server issues. Visit Activision’s Server Status page to ensure there are no outages or disruptions in your region.

3. Improve NAT Type

Your NAT (Network Address Translation) type plays a big role in connectivity:

• Open NAT (Type 1) is best for seamless matchmaking and connection to other players.
• To change your NAT type:
  • Log into your router settings.
  • Enable UPnP (Universal Plug and Play).
  • Forward the required ports for Call of Duty:
    • TCP Ports: 3074, 27014-27050
    • UDP Ports: 3074, 3478-3479, 27000-27031, 27036
  • You can find detailed port-forwarding guides on websites like PortForward.com.

4. Lower Your Ping

• Close Background Applications: Shut down apps like Netflix, Discord, or downloads that may consume bandwidth.
• Adjust Game Settings: Some Call of Duty titles allow you to view your ping in the settings menu. Use this to monitor your connection during matches.
• Choose Low-Latency DNS Servers: Change your DNS settings to faster, more reliable servers, such as:
  • Google DNS: 8.8.8.8, 8.8.4.4
  • Cloudflare DNS: 1.1.1.1, 1.0.0.1

5. Upgrade Your Hardware

• Upgrade Your Router: If your router is outdated, consider a gaming router like the Netgear Nighthawk XR500 or ASUS ROG series, designed to prioritize gaming traffic.
• Invest in a Low-Latency Gaming Setup:
  • Use gaming consoles or PCs with a reliable network card.
  • Enable QoS (Quality of Service) settings on your router to prioritize Call of Duty traffic over other devices.

6. Monitor Packet Loss

• If you're experiencing stuttering or packet loss:
  • Test your connection with a tool like PingPlotter or Speedtest.net.
  • Contact your ISP to resolve high packet loss or consistent lag spikes.

7. Restart Your Network

• Power Cycle Your Router and Modem:
  1. Turn off your router and modem.
  2. Wait 30 seconds, then turn them back on.
  3. Reconnect to Call of Duty servers.

8. Play During Off-Peak Hours

When servers are crowded (evenings or weekends), connectivity can suffer. Try playing at less busy times to avoid server congestion.

By applying these steps, you should experience a noticeable improvement in your Call of Duty server connectivity. Don’t forget to test each change and monitor your ping or lag in-game to see what works best for your specific setup! If you need further assistance or details, feel free to Stay Updated.

Activision sometimes moves or adds servers to meet demand. You can check server status and updates directly at Activision Support.
