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. 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.
It is seen in the graph below that we observed losses of > 80 at 9:09, 9:39 and 10:09 and zero loss at 8:38am and again at 10:38. Also the Round Trip times increased from ~ 200 msec to over 450 msec. The route from SLAC to www.mahsa.edu.my passes through AS4788.
