- Why do I have to use this Blizzard Downloader? Why can't I just download the file normally?
Blizzard Entertainment is currently testing a Blizzard Downloader that is based upon BitTorrent, an open source technology which is freely distributable pursuant to the MIT License. Click here for more information. This test will help determine how we will proceed with future file distribution methods. Note that this utility is only active when you are downloading files, and that only files associated with the file that you are downloading are uploaded. Blizzard will not upload any other files, or obtain any personal information about you as a result of this activity.
- What is BitTorrent and how does it work?
This technology allows users to download large files without being limited by a host's bandwidth by using a peer-to-peer protocol.
Each person downloading the file will offer a portion of their upload bandwidth to allow other users to download the same file. By using the upload bandwidth only, the individual user will not see a decrease in their download speed - in fact, the more users there are downloading the file, the faster everyone's individual download speed will be.
- Why would I want to use BitTorrent?
If you have ever downloaded a file from the internet, you know it can be time consuming and is often limited by the host's available bandwidth. By using BitTorrent, the user is not limited by any one host's capabilities - instead, the files are distributed across a wide range of users, allowing for a quicker download for everyone. By using the upload capabilities of each downloader, the overall file distribution is much more efficient for everyone.
- I'm constantly displaying a "connecting to peers" message.
If you are using a firewall, you will need to ensure that ports 6112, 3724, and 6881 through 6999 are open in order for BitTorrent to connect correctly. If you are using a router, you may also need to set up port forwarding for these ports. You may need to refer to your firewall/router's documentation for instructions on opening ports and setting up port forwarding.

- I'm getting a slow download speed, what can I do to improve it?
If you are using a firewall or router, be sure that port orts 6112, 3724, and 6881 through 6999 are open and forwarded to your computer and only your computer. You may need to refer to your firewall/router's documentation for instructions on opening ports and setting up port forwarding. Also, make sure that no other programs that use bandwidth are running while attempting to use the Blizzard Downloader.
Please consult our Slow Download Speeds using the Blizzard Downloader page for more information.

- I go to college and my network administrator blocked the ports you mentioned. What can I do?
Some college or universities may still block Bit Torrent Connections. Unforunately, this limitation is set by the network administrator.
- The downloader is crashing/freezing. What do I do?
Many customers report that issues such as these can be remedied by updating their network card drivers. Please take a look at our Blizzard Downloader Freezes, Crashes, or has High CPU Utilization page for more details on problematic hardware as well as other possible solutions.
- The option to change my connection speed is gone. How do I change the speed to match my connection?
The latest version of the Blizzard Downloader has automatic Bandwidth detection and balancing that achieves an optimal amount of communal bandwidth. As the 'Connection Speed' option is no longer needed, it was removed.
- The 'Estimated Download Time' is blank! How long is the download going to take?
The 'Estimated Download Time' field will not be displayed until you have connected to an optimal number of peers and your connection speed has reached optimum levels. This is to prevent inaccurate estimates from causing confusion.
