I doubt that.
There are some sites that give me only 10-20kBps speed during day but at night (between 2AM - 6AM) even those sites start giving better speeds and at the same time this veendam server also start showing better speeds. something somehwre is wrong with JIO. If anyone has any other ISP then maybe try that. I have started a smiliar thread in airtel section to see if airtel is also having the same issue.
