Korean server high ping

been playing on the korean league of legends server through the korean nodes. I was getting a constant 50 ping earlier this week but now ive been getting 100+ for the past couple of days. Im playing from hong kong

Is there something wrong with the servers or is it my internet that has problem?

Thanks
