Introduction
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 sites in Ukraine around the time of the Russo Ukraine war in February 2022.
At the start of the war, the PingER project was only monitoring 2 sites in Ukraine: mail.kipt.kharkov.ua and ns.kiev.ua. Since then we have added 5 more sites.
In addition one of the monitored sites (mail.kipt.kharkov.us) was a PingER Beacon site that was monitored from 11 PingER sites around the world, in particular, the closest monitoring site from Ukraine was DESY in Hamburg Germany

There are some notable changes in some of the Round Trip Times (RTT) for 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, 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 RTs.
- There is an increase in RTTs seen from DESY, Hamburg Germany to the Kharkov Institute of Physics and Technology starting 18:00 March 2, 2022 GMT
- 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.
I also note that all the web servers (except ns.kiev.us) that PingER is monitoring are still serving web pages.
