Server Issues

Ever since URF Mode was released I've been experiencing major lag and server issues in ranked, before anyone says it's because of my computer or internet connection I was playing just fine and made it out of Bronze 3 and into Silver 4 with no complications. After URF was released I started experiencing things between moonwalking backwards in one location and then flashing to another location (repeatedly), Minions not disappearing after death, not re-spawning, game randomly "Attempting to reconnect", and sometimes enemy or ally teammates not appearing on the map.
