Airtel has acknowledged and is in the process of reverting.   Thanks all for your input.

I don't know what's less surprising, Tata making sure you see the entire internet (wink wink), or Airtel leaking routes... :)

I have tried to reach out to Airtel, no response yet, but yah I could see my issue being due to them 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.
