[Gameplay] Riot's server issues while in a ranked game

During a ranked game playing ezreal, I encountered a huge ping spike of 3k ping, afterwards disconnected, thought it was me only but it turns out everybody was moaning in chat about it. It continued reappearing several times until at once it happened during a teamfight and Vi's autoattack on got her a quadra, losing us the teamfight and giving them a tremendous head, it continues appearing again causing many of us to die, at the end leading to our loss. This was in my last ranked game as ezreal. I've almost never experienced server issues with riot, it's so rare but this time it happened in a ranked game which made me lose 16 LP as for some reason, it wasn't a loss prevented. I'm aware of the complexity of the ranking system and I'm not begging for any LP back, I'm posting this as to make riot aware of some problems. Thanks for reading :)
