BSNL-Level3 bad routing case
Quick analysis of BSNL-Level3 bad routing issue
I can see BSNL having pretty high latency again with most of Europe again. It seems like they are using Level3 Communications AS 3356 along with Tata-VSNL for upstream. With Level3 transit BSNL has badly screwed up reverse path causing very high latency and awful bandwidth.

Expected latency values here should be around 150ms. A packet should not take more then 150ms round trip between Radaur, Haryana to Munich located server.
