Ping/Jitter Problems

ok so the other day when i was testing my ping on pingtest, i was getting the weirdest results, giant jitters all the way from 20-50 or more, it was crazy, i thought something was wrong with pingtest.net at first, but then the next day it sorta fixed, and it only happens when i ping certain places now, but even on the line quality test in the tools section of this site which seems pretty legit, my results were great a month ago, now when testing small packets its fine, but as soon as it starts to test with big packets it gets insane spikes and pretty much stops the testing because of it, i don't know whats happening here but i i tested last night and got weird results when not playing games, and i tested tonight while both xbox's were connected to make sure nothing weird was happening because of the load on the connection, if its related to the load, it should be fixed by upgrading my bandwidth which i plan to do in about a week, it doesn't make any sense to me this would be causing it tho, could other people plz test there lines to make sure its not a thing happening to all shaw customers or vancouver area customers right now, plz check my line test results here http://www.dslreports.com/testhistory/1856317/ab15f the test to note is the first test i made at 5am on the 30th after having some of the weirdest lag i have ever had on the last 2 games i played, u can clearly see the spikes, then 1 more bad test after that, and 2 almost normal ones before they started to get really weird when i tested today
