I have come across this issue a lot, rn I have airtel and the pings to twitter.com are no less than 140 ms, before airtel i used to have bsnl ftth, and even in that my pings were around the same 150 mark, is this a twitter issue? it surely must be, but then again i read somewhere that they use aws and usually it works flawlessly with other sites, does anyone have a possible explanation? and what are your ping times to twitter?
