Games being one-sided because of lag.

Was in game today, for two games, both games my entire team for each game 4 of us or all 5 of us would be hit with some super lag that would cause us to disconnect from the server. This wasn't the case for the opposing team as it dissipated as they were attacking our nexus. We had been out of game for 2 whole minutes. I don't know what is going on. I hope Riot will look into this. It seems to be always the Blue side for me that is "infected".
