I got logged out of a champs game because of "high traffic"

wtf is going on?!

i keep getting kicked out too! happened last week so i figured it was an internet issue, but the same thing is happening now as well, this only happens when i play champions. i have spent a **bleep** ton of money on this game to get treated like this 

i've been kicked out of 2 games already so far, easily winnable ones!
