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.

Map of Oblasts (Regions of Ukraine)
There are 24 Ukrainian Oblasts (see Wikipedia). We monitor sites in 16 of the Oblasts.
Number of Ukrainian hosts monitored from SLAC by day
As the war progressed we added more Ukrainian hosts to the list of monitored sites, and lost a few.

Median value of medians is 180.215
Map of monitored sites
Using https://batchgeo.com/ and the above table of the "Coordinates of Ukrainian ping targets" to derive https://batchgeo.com/map/a1a293ce71040705f722f1b45064b628(click on link or see below):
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:
Proximity Description | Value |
Fallen & occupied by Russian forces | 4 |
Surrounded by Russian forces | 3 |
Partially surrounded by Russian forces | 2 |
Russian forces nearby | 1 |
Russian forces not nearby | 0 |
We then plot the IPDV and proximity for each Ukrainian host monitored and look at the correlation between the IPDV and proximity
IPDV and Proximity for the Ukrainian hosts | Correlation between IPDV and Proximity of Russian forces (Mid March 2022) |
---|---|
There is a small positive correlation between the proximity and IPDV.

There was no response to pings from SLAC to www.kntu.net.ua between 16:30 May 30 and 01:00 Jun 2, 2022 GMT. Then again Jun 27 thru Jun 29.
On November 10, 2022 the Russian defence minister Sergei Shoigu on Wednesday announced Russia would pull out its troops from the southern Ukrainian city of Kherson, the first and only regional capital to be captured by Russian forces since they invaded Ukraine in late February. By November 13, Ukraine now occupied Kherson and the west bank of the Dnipro river.
The suspiciously low RTT of just over 142 msecs may indicate the host has moved West out of Ukraine and is now closer to the US
