Americas region realm list by datacenter (Classic)

Realms in the Americas Classic region are hosted for Blizzard in several datacenters across the United States and Australia. They are located in:
 * Chicago, Illinois
 * Los Angeles, California
 * Sydney, Australia

While new players often wish to choose a realm matching their own time zone, those realms may actually be located far away from them. For example, some servers in Los Angeles have realms on US Eastern Time, and some servers in Chicago have realms on US Pacific Time. Instead, players may first wish to pick a datacenter to which they have good internet connectivity.

To that end, this is a list of US realms organized by datacenter, battlegroup, time zone, and realm type.

Blizzard also has posted a way to run a trace-route to the Americas (and other) datacenters.

Time zones
The following tables have abbreviated time zones in an effort to conserve space. Those abbreviations and the full time zones are:

Chicago
When doing a traceroute to servers in Chicago, please trace to the following IP address: 63.240.161.189

Los Angeles
When doing a traceroute to servers in Los Angeles, please trace to the following IP address: 12.129.209.68

Australia
Realms physically located in Australia were opened on October 28, 2014. For matchups only involving players on Oceanic realms, instances (like battlegrounds or raids) will also be physically located in Australia. However, should matchups involve players on non-Oceanic realms, instances will be physically located on whichever server is closest to the leader.

When doing a traceroute to Oceanic realms, please trace to the following address: 103.4.115.248
