Have not had any such issues. But I am getting very low (~5 to 10 mbps) upload on international servers like leaseweb and gtt, frankfurt or even singtel SG. Don't know if airtel is capping upload or what.
Mine issue got resolved last hour or so.. right now getting full speed on speedtest and fast.com atleast.. tried international servers you mentioned and it looks uploading speed is capped to 100 Mbps for me too..
