One of my friends is from IIM Kashipur, so I will be sharing his experiences, which will only refer to the hostel facilities provided by IIM Kashipur.
We have an online portal where we can post any issues with hot water, RO filter replacement, tube light replacement, or any other hostel-related issues. The problems are resolved on a priority basis within a few days. Honestly, hostel facilities are one of the best things you get in IIM.
