Disconnected multiple times in Brazil Server

I play a lot in the Brazil server. Of Late I have been disconnected at least 2-3 times a game. I have bought to many champions and skins for this to happen this frequently. Riot needs to fix this in their server. My friend lives in Brazil and this used to never happen. When spectator mode went down I just could not connect. Now it just drops me and I have gotten in the past 4 days two 5x20 minute afk penalties which are not my fault. Its frustrating and very irritating. As I did nothing wrong. This is all because the server of late is very undependable. Please fix the server. Any suggestions how to fix this so it does not keep occurying? I cant play with my friends and its very discouraging as well. Thanks for any help you can provide. My name on the Brazilian server is I G O O F Y I. Thanks
