Interesting. An ICMP packet dropped when busy. Well, it seems as
if there is only a hair's difference between when an ICMP packet is
dropped and when an IP packet is dropped.
If you are busy, you are busy, right?
I know that I was getting zero packet loss for many many basic routes
this time last year that are now losing packets. I think that a network
is in great shape when the packet loss is at a sheer minimum. Even one
percent packet loss can be felt as substantially more degraded than
perfect transport.
Just like ra.net, I use pings to monitor one aspect of overall performance.
Me and ra.net are not alone.
