1/ open a DOS window
2/ run the command: tracert 188.8.131.52
Take a screenshot of the output and post it here.
Next, do the same when the EB is running smooth.
This should help to determine if this is a server or connection issue. I'm leaning towards the 2nd as I'm not experiencing these issues.
Thanks, it hasn't been running slow for me to take a screen shot though.
