A traceroute to the State Bank of India (sbi.co.in) is 27 hops, 358ms RTT, and routes Amsterdam->London->NYC->San Jose->Singapore->India. Then again, a traceroute to Reliance (www.rcom.co.in) is only 13 hops, 159ms and routes from London directly to Mumbai over Flag Telecom (n.b. a wholly owned subsidiary of Reliance telecom), showing that not everyone has bad routes. Then again, if one of the global network infrastructure leaders didn't have a good route to their website in India, who would? As an interesting sidenote, it seems that some of India's largest corporations do their hosting in the US. Tata and Aditya Birla both even host with the same SF ISP, Cybercon.

PBwiki's network was not involved in this case, however. A virtual machine located in Amsterdam and not on PBwiki's production network traced connections to several machines located in India which are also not on PBwiki's production network. It's possible that there may have been some temporary BGP issues involved, but I find it more likely that the global network is still dealing with the FLAG fiber cuts. http://www.dailywireless.org/2008/01/30/oceanic-fiber-cut/ Paul – thanks for the comment.

Such routing may be indicative of faulty BGP setups somewhere along their edge routers.
