Yes, your location as well as your ISP should have an impact on the lag in a game. It's quite easy to tell that it wasn't PC lag at all, example when you're trying to run up the map with those boulders coming down at you, it's sometimes quite hard to dodge them because of the server lag. Same for the 2-10 stage. With those blue laser things going up and down the map, they're quite annoying to dodge at times because of the lag.
