Riot, can you check with internet providers and see if it's bothering your servers?
I've been off league all day until just recently where my internet was perfectly fine. As soon as I get into game I start lagging even with perfectly fine ping (like 90-120 ping which is normal for me) then at around 0:56 my net just turned off then came back on repeatedly resulting in a lose.
I got put on a 5 game afk wait thing which I can't really be upset about cause I deserve it since it was ranked even tho it wasn't my fault at all. This only seems to happen when I get into a game as well, im currently on the client and having 0 internet issues as before.
I never get any type of issues outside of being in game on league. It's really annoying
