PingER uses the ping facility to measure the Round Trip Time (RTT) between about 20 monitoring sites and target hosts in over 160 countries (over 10,00 pairs of monitor-remote target site). Every 30 minutes the monitor sends up to 30 pings at one second intervals to each target until there are 10 responses, and records the data which are daily gathered, archived, analyzed and presented at the archiving site.
A timeline for COVIUD-19 can be found here. Note that for Europe, US and Canada the Christmas/New Year season (end November thru 2nd week in January) may be expected to change the behaviorbehaviors.

The PingER monitor at SLAC, Stanford University in California currently monitors about 100 hosts in China. Using the pingtable.pl web page we selected daily aggregated data from SLAC to China for the last 365 days and looked at various metrics derived from the RTTs. Since many of the targets are Universities that may have taken lockdown measures and sent many students and staff home, we decided to look at the overall impact on SLAC to China pings. To do this we scroll down the pingtable.pl page to a summary table

Looking at the Inter Packet Delay Variation (IPDV, ) a measure of the variability between adjacent ping packet RTTs there is some evidence that the variability reduced between 28th 18th Jan and March 10th 2020. Whether this has anything to do with COVID19 I do not hazard a guess. I do note that the first person in China to die of the CORONA-19 virus was reported on January 10th, and by January 31st there were 9,720 cases in China.
I can see nothing similar when looking at the US and Canada (N. America) IPDV data, maybe the effect is later in the evolution of the virus' impact.
