PingER results show a clear decrease in minimum, average and maximum RTT. These are quick and dirty graphs that I will tidy up in due course (click to see full size).
Note the long-term stable minimum of 150 ms jumped up to around 158 ms at about 7.30am (Pacific) on May 29 before dropping to around 140 ms at the time of the route change-over. The reverse step was seen after the change back.
