The high delay behavior isn't a link flapping. I ran a 12 hour test today(Feb 22, 2017) between my home in Illinois and two servers in Japan. Approximately 1% of the round-trip times were over 20 seconds. The high delays were all in the Japan -> Illinois direction. [Similar delays can sometimes be seen within the United States, though the rate is much lower.]
There may be a relationship between the high delays and increased losses. [Consider how one might implement rate limiting.] On Wed, Feb 22, 2017 at 1:24 AM, Hal Murray <[email protected]> wrote: > > [email protected] said: > > Round trip delays of 20+ seconds are surprising to me.
