I was enthused to hear they are opening up india, in part because our simulations team is at nitk. I wish there was a way to get starlink in touch with mohit, cc'd. They've been simulating transport various congestion controls vs AQM and FQ technologies at the rtts common to starlink and viasat of late, and could use better numbers to plug in at the very least.
