Looks like some one is using his upload speed to at least 50% of max speed possible on the 30meg service...
snap just like me..
At between 3.30pm - 4.15pm the Upload went to 130% full speed on upload to Google docs and Youtube. (they were reporting higher than the allowed 2Mb/s upload) This crashed the other application ktorrent for some reason...
If you are not uploading then you have upload restriction some were, also note that your ping returns to normal at 12am ish so its not perminant. What did you just turn off.
or VM fixed it..
