Lag over 500ms

For the past 3-4 days im experiencing any issue with Latency/ms not all of the times (starting from 150ms to 600-700ms). This thing is happening literally out of the blue while im playing and it doesn't get fixed. I have done anything possible to fix that but it seems that its not a fault of my internet connection but somethings wrong to the game servers. I'm restarting the game for a few times but still doesn't get fixed. Propably 30 minutes after its getting fixed on its own or something. Does anyone else have the same problem? Or how i can fix that?

Same, since 0.1. tried every fix there is out there and nothing helps. A lot of people are experiencing this and no one from GGG side cares.
