Going to http://www-wanmon.slac.stanford.edu/cgi-wrap/connectivity.pl?format=csv&rawdata=pinger.usindh.edu.pk&days=6&monitor=pinger.pern.edu.pk and http://www-wanmon.slac.stanford.edu/cgi-wrap/connectivity.pl?format=csv&rawdata=pingerjms.pern.edu.pk&days=6&monitor=pinger.pern.edu.pk we collected the data for past 7 days and plotted it in excel to see the curves for Average RTT and Min RTT.
Min RTT from Pern Islamabad | Average RTT from Pern Islamabad |

Looking at the graphs one can see that there are rapid fluctuations in the data values for each node. Because of which the graphs show a scattered plot with a number of data points above and below, which seem to be on the same point on x-axis. However looking at the spreadsheet, it is observed that two data values are collected for each half an hour, and these two values fluctuate by about 0.3 ~ 0.4 ms for PoP node while it fluctuates by 0.63ms for usndh non-PoP node. Although we don't know the reason for this fluctuation , however we know that this fluctuation is continuous for both of the nodes and for all 7 of the days.
