IntroductionIntroduction 

This page provides information on ping response times measured every 30 minutes from the SLAC National Lab (40 miles south of San Francisco in California, US) to over 25 sites in Ukraine around the time of the Russo Ukraine war starting in February 2022. See https://www.usnews.com/news/best-countries/slideshows/a-timeline-of-the-russia-ukraine-conflict for events leading up to the crisis in 2022,  and see https://en.wikipedia.org/wiki/Timeline_of_the_2022_Russian_invasion_of_Ukraine for progress of the 2022 war.

Minimum RTT

As a check that each target host was in Ukraine we plotted their distance from SLAC versus the minimum RTT recorded for March 2022. The correlation between minimum RTT and distance from SLAC gives us some confidence that the hosts are indeed in Ukraine.

Jitter (Inter Packet  Delay Variation - IPDV)

We might expect the network performance to hosts that are in a war zone may be degraded and show up as more variability on the RTTs. A sensitive measure of variability of the RTTs is the Jitter between adjacent measurements. We use a derivation of the Inter Packet Delay Variation (IPDV) to estimate the Jitter from the Ping measurements (see https://www.slac.stanford.edu/comp/net/wan-mon/tutorial.html). In addition we characterize the proximity of the war to a host in Ukraine by its proximity defined  as:

...

We then plot the IPDV and proximity for each Ukrainian host monitored and look at the correlation between the IPDV and proximity

Slavyansk (or Sloviansk)

According to Wikipedia "Sloviansk was one of the focal points in the early stages of the 2014 pro-Russian conflict in Ukraine as it was the first city to be seized by Russia-backed military troops.^[7][8] It was retaken by Ukrainian forces in July 2014...On 4 July 2022, The Guardian reported that, after the fall of the Luhansk oblast, Russian invasion troops would continue their invasion into the adjacent Donetsk oblast to attack the cities of Sloviansk and Bakhmut. In early September 2022, Ukraine began a major counteroffensive, regaining several settlements in the Kharkiv region. This relieved the pressure on Sloviansk with the fall of Lyman to Ukrainian forces on October 1st 2022."
