Yes, exactly. Exact location is needed to be known. I live in a small town adjacent to Kolkata and I used Alliance for 2 years. The LCO in charge is a lowlife, so the experience was likewise. I never knew that a wired broadband connection could be that inconsistent. Internet was there a minute, next minute, no. Finally my luck cracked out and their ONT device stopped working. Didn't know what a blessing it was at that time. I almost begged the LCO to provide me a replacement ONT, but he kept pushing for 2500 rupees for it. It felt unprincipled to me, so I started looking for alternatives. Found Hathway broadband, this is in 2020's second half. Since then absolutely no complaints. 24x7 connection. If it goes out usually there's a notification few hours prior. In late 2021, Jio and Airtel also started their service here and first month trial was free (I guess trials are free anyway lol), so I tried both of them for a month. Airtel's speed was excellent, more than advertised, but latency was shite to European, Singaporean and sometimes even to Mumbai servers (I play CS Go), so despite my intention of staying with them I simply couldn't. Then it was Jio's time. Their latency was fine, on par with Hathway's, but they throttled torrents, rather heavily at times, so couldn't stay with them either. Back to Hathway now, but I hear that Airtel latency issues are somewhat solved, so I plan to move back to them soon.
There's no ISP in India which provides quality seeding, whereby you can access international websites at same speed as advertised speed of the ISP. Both Airtel and Jio are good at the moment, Jio just throttles torrents from my experience, Airtel doesn't.
PS: Whatever happens stay away from those shitty, lowlife LCOs. They will make your life hell.
