I also experienced significantly slow and unstable international traffic in the past few weeks, especially when viewing websites in Asia and China.

 

This morning it was even worse as I basically couldn't load any Chinese websites.

 

Meanwhile my university connection can access them smoothly.

 

 

 

I've done some traceroute for troubleshooting.

 

China:

 

pan.baidu.com 2D vs AUT

 

qq.com 2D vs AUT

 

weibo.com 2D vs AUT

 

Singapore:

 

worldoftanks.asia 2D vs AUT

 

Japan:

 

yahoo.co.jp 2D vs AUT

 

UK

 

bbc.com 2D vs AUT

 

 

 

From my analysis it seems there are issues connecting USA and China via gtt.net networks. Not sure if that's the actual problem.
