IntroductionIntroduction
This page provides information on ping response times measured every 30 minutes from the SLAC National Lab (40 miles South south of San Francisco in California, US) to over 25 sites in the 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.
On 24 February 2022, the Russian President Vladimir Putin ordered an invasion of Ukraine by Russian Armed Forces previously concentrated along the border. At that time the PingER project was At the start of the war we were only monitoring 2 sites in Ukraine: mail.kipt.kharkov.ua and ns.kiev.ua. Since then we have added 4 over 20 more sites.
In addition one of the original two monitored sites (mail.kipt.kharkov.us) was a PingER Beacon site that was monitiored monitored from 11 10 PingER sites around the world, in particular, the closest PingER monitoring site from the Ukraine was DESY in Hamburg Germany

Summary April 9, 6pm California time
There are some notable changes in some of the Round Trip Times (RTT) for the:
- The Odessa I. I. Michnikov National University a step up starting Feb 27, starting around 14:00 GMT, and then a larger step down on Feb 28 around 20:00 GMT.
Then again on Mar 2, 2022 there is a marked increase in RTT between 16:00 and 20:30. - The Western Ukrainian National University, which is farthest from the invading forces, saw a step up starting around 9:00am GMT Feb 25, 2020, then steps down on Feb 28 around noon and 20:00 GMT. Then on Mar 2 16:30-20:00 there is a burst of increased RTTs.
- There are a couple of bursts of increased RTTs seen from SLAC to Kyiv Academic University on Feb 28, 2022 11:00-12:00 and again on Mar 2, 17:00 - 18:30GMT.
- There is a step increase in RTTs seen from DESY, Hamburg Germany to the Kharkov Institute of Physics and Technology starting 18:00 March 2, 2022 GMT.
- The Simon Kuznets Kharkiv National University of Economic, Kharkiv saw a step increase in RTT of about 8ms around 10:0am Mar 3, 2022 GMT
- The Vinnytsia National Technical University saw an RTT step upward of about 3 ms around 16:30 Mar 3, 2022 GMT.
- We have been monitoring the Kharkiv Institute of Physics and Technology since 2004. It was no longer pingable from SLAC by name mail.kipt.kharkov.ua or address 193.239.180.1 after 13:15 Mar 3, 2022 GMT (5:15 am Mar 3, 2022) and returned around 7:30am Mar 4 GMT. Also the web page https://mail.kipt.kharkov.ua/ no longer responded during this period.
Also the RTT from SLAC to this host noticed a step increase of almost 5msec around 2100 hours GMT followed by another step increase.
No response was seen from pings starting around 19:00 3/10/2022 GMT. Also the name mail.kipt.kharkov.ua did not resolve to an address. Then it responded by address (but the name did not resolve) again around 15:30 3/16/2022 GMT, also, the web site did not respond. By 1:02pm 3/17/2022 (California time) the web page was again responding and the name service was working for mail.kipt.kharkov.ua giving the same address (193.239.180.1) as before the outage. Then following Mar 23 22:00 GMT it again stopped responding and started responding again around 15:00 Mar 25, 2022 GMT.
The effects are more marked in the ping measurements from DESY, Hamburg, Germany since it is much closer than SLAC to the Ukraine. Comparing the minimum RTT of (~44ms )prior to Mar 1st with that (~33ms) after 18:00 on Mar 19, there is a 11ms change.
This is confirmed looking at the RTTs between SLAC and mail.kipt.kharkov.ua and comparing the minimum RTTs prior to Mar 1st (~190ms) with those after Mar 16 (~180ms) indicating a drop of ~10ms. - The National University of Shipbuilding, Mykolaiv (www.nuos-international.com.ua) saw no responses after 21:07 Mar 5 and before 02:37 Mar 6 when it started to respond again. It again no longer responded to pings after the early morning of Mar 21, 2022 (GMT).
- The Chernihiv National University of Technology site www.chnpu.edu.ua saw a step increase of 20ms plus some instability and losses after Mar 8 07:07 and until just before Mar 8 16:37. The host was no longer pingable from GMT 14:30 Mar 11, 2022 onwards. Also, the website no longer responded. It again started responding from GMT 09:30 Mar 16, 2022 onwards until the early morning of Mar 21, 2022 (GMT) when it stopped responding to pings.
- The Lviv State University of Physical Culture, also saw a similar step increase of 20ms plus some instability and losses after Mar 8 07:07 and until just before Mar 8 16:37.
- The https://www.hostmaster.ua web site originally in Kyiv moved to California as www.hostmaster.ua.cdn.cloudflare.net (104.18.24.87) sometime after Mar 9 and before Mar 15. The host hostmaster.ua (193.29.222.26) remained in Kyiv. Also according to https://hostmaster.ua/news/?pr20220226 'As of 2/.26/2022 the .UA domain registry company "Hostmeister" has transferred to European countries servers that ensure the operability of the .UA domain. Previously, the servers were located in Kiev.'
- PingER has been monitoring ns.kiev.ua since the year 2000. Up until March 4th, 2022 the daily inter-packet-delay-variation or jitter (see https://www.slac.stanford.edu/comp/net/wan-mon/tutorial.html) of the ping RTT was consistently below 0.7ms. Since then it has climbed to over 7ms.
- The following hosts have not responded to pings for extended times:
- Chernihiv National University of Technology (www.chnpu.edu.ua) stopped responding early morning of Mar 21, 2022, then starting Apr 16, 06:37 GMT we were able to get a response albeit at a new IP address (193.151.106.66=>46.149.36.68).
- Kharkov Institute of Physics and Technology (mail.kipt.kharkov.ua (193.239.180.1)) stopped responding Mar 10, 19:00 GMT; restarted Mar 16 15:30 GMT; stopped responding Mar 23, 22:00, 2022 GMT; restarted Mar 25 15:00, 2022 GMT; stopped responding Mar 28 10:14 GMT. In fact no hosts in the range 193.239.180.0/24 responded Apr 22, 17:00,2022 PST. Then it restarted responding Apr 29 12:30, 2022 GMT only to stop again Apr 30 19:00, 2022 GMT and restart again May 5 12:00, 2022 GMT.
- The National University of Shipbuilding, Mykolaiv (www.nuos-international.com.ua) saw no responses after Mar 5 21:07, 2022 GMT and before Mar 6 02:37, 2022 GMT when it started to respond again. It again no longer responded to pings Mar 22 00:07, 2022 GMT but restarted responding Mar 22 00:36, 2022 GMT.
- The Institute of Mathematics of NAS of Ukraine, Kiev (www.imath.kiev.ua) did not respond from Mar 22, 16:00 GMT until Mar 23, 14:00 GMT.
- The Ukraine Hostmaster (www.hostmaster.ua) for the Top Level Domain UA did not respond between Mar 11 22:30 GMT and Mar 12 06:00 GMT.
I also note that all the web servers (except ns.kiev.ua, www.kipt.kharkov.ua (the web site for mail.kipt.kharkov.ua), and www.hostmaster.ua (moved to California sometime after Mar 9 and before Mar 15)) that PingER is monitoring and are responding, There is not much to see, the only marked change is from the Western Ukrainian National University, which is farthest from the invading forces. This site sees a step increase in Round Trip Times (RTT) around 9:00am GMT Feb 25, 2022. I also note that all the web servers PingER is monitoring are still serving web pages.

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.

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.

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."
