Latency Spikes - Sao Paulo

Hello.

Since friday 7th i've started noticing lag spikes, sometimes on the 300ms range and sometimes it goes to over 3k, making the game unplayable.

It doesn't matter if it's in my hideout or mapping.

Im currently playing on Sao Paulo server and already verified that my connection is OK, since i play other online games.

I read other posts about this but GGG never made an acknowledge and it's worrying.

Thanks!
