I have shared about this leak with known contacts in their NOC. Thanks. On Fri, Nov 16, 2018 at 4:05 AM Tom Beecher <beecher@beecher.cc> wrote:
I don't know what's less surprising, Tata making sure you see the entire internet (wink wink), or Airtel leaking routes... :)

I'm not sure what is supposed to be there for 6453_9498 but I suspect not nearly as much as is currently present (only 4637 listed here for brevity).
huh... us-carrier -> tata -> airtel -> telstra .. that seems TOTALLY PLAUSIBLE.. no.

Marcus,
From route-views output, it looks like AS9498/airtel is probably leaking your route between two of its upstreams (AS6453/Tata and AS4637/Telstra) overseas, funneling some of your traffic through their router.

You might try halting advertisements to your AS4637/Telstra peer while you contact AS9498.
