Stop using icmp to measure ping.
There is now hard evidence this is unreliable because of measures isps and teir 1 networks take when nodes go bad.
They blank out info on icmp so you cant see what is going on.
UDP shows up a lot of the time.
Surely you can then give the your customers hard evidence to go to their isps with when they have problems.

time to take notice.
this is causing the vast majority of input delay.
