Everyone was dcing. I want my LP back. PLEASE RIOT.

I was just in a ranked game with all my friends, and for some reason all 4 of my teamates kept lagging in and out, and I was the only one who wasnt lagged. The enemy team had 4 people that didnt dc. I WANT MY LP BACK, come on man ;(. They need to fix these problems. Seriously though, did anyone else have this problem or was it possible everyone was ddosed.
