A massive route leak initiated by Telekom Malaysia (AS4788), starting at 8:43 June 12, 2015 UTC, caused significant network problems for the global routing system until about 10:40 June 12, 2015 UTC. Primarily affected was Level3 (AS3549 – formerly known as Global Crossing) and their customers. See http://www.bgpmon.net/massive-route-leak-cause-internet-slowdown/ for details. This study shows the effects as seen by PingER monitoring hosts at SLAC and at the University of Malaysia.
Correlation for Level3 AS

- pinger.uum.edu.my has not been accessible for several months.
- there is no obvious correlation (increase in losses or RTT) in degraded ping performance and the time span of the injected route problems for www.ait.ac.th, www.ait.asia, www.rmutsv.ac.my, www.usim.ac.my
- www.mju.ac.th has not been accessible for several days
Correlations for Malaysian hosts seen from SLAC
For or the 26 Malaysian hosts monitored from SLAC on 6/12/2015 looking at the 95 percentile frequency losses as a function of hour of day (see http://www-wanmon.slac.stanford.edu/cgi-wrap/pingtable.pl?file=packet_loss&by=by-node&size=100&tick=hourly&year=2015&month=06&day=12&from=EDU.SLAC.STANFORD.N3&to=Malaysia&ex=none&only=all&dataset=hep&percentage=any) then apart from the hours of 9:00 and 10:00am UTC the losses are zero. The two majn contributors are: www.mahsa.edu.my and www.mmu.esu.my. Below are shown the RTTs and losses for these hosts on 6/12/2015.

Just to illustrate that this is not normal behavior for say www.umt.edu.my we show the ping performance over longer period below:
