My name is James Baldwin, and I am a network engineer here at BioWare. We are continuing to look into reports regarding ongoing latency and lag issues within the game. While not all in-game lag issues are caused by network latency, we have experienced several network events in the past weeks which have negatively impacted play experience for some. We are continuing to work with our vendors to investigate ongoing issues as well as identifying end user ISPs who may be experiencing high latency or packet loss.

To help us more quickly identify these issues I am beginning this thread to better organize our network latency investigation.

If you believe you are experiencing issues due to network latency, please provide the following in this thread:
  • Time of day you feel latency is worst (if it is restricted to a particular time of day, please include your timezone)
  • Your traceroute output at the time you are experiencing the issue using the 'code' tag (see below for details)
  • Your traceroute output when you are not experiencing the issue as a comparison
To help us get maximum benefit from this thread to help you, please avoid other comments that are not reports on this issue. Thanks.

If you have output from another tool, e.g. winmtr, feel free to include this after you have included output from Microsoft's tracert.

Getting your traceroute output

You can access traceroute through a Command Prompt. Click the Start Menu and type "cmd" or "command". When the shell opens and you are presented a prompt, type one of the following:

If you play on an East Coast server: tracert
If you play on a West Coast server: tracert
If you play on a European server: tracert

When providing the traceroute output, if you are worried about providing information regarding your public IP address, remove any lines up to and include your public IP by replacing them with ***.

Please note: if you are experiencing less than 70ms of network latency and 0% packet loss, you are most likely not experiencing network-induced lag in the game.

Here's what we're looking for as an example:

Time of day: 9PM-10PM Pacific

Tracing route to over a maximum of 30 hops

  1     1 ms     1 ms     1 ms  ***
  2     1 ms     1 ms     1 ms []
  3    68 ms    39 ms    40 ms []
  4    42 ms    42 ms    42 ms []
  5    42 ms    43 ms    42 ms

Trace complete.
Thank you in advance for your help!
