This sadly is an issue due to the internet cables in the red sea being cut, this has caused massive packetloss and latency and repairing this may take weeks or months and there is no fixed date yet
Middle East, South and Southeast Asia are mainly affected by it as much as I remember.
Also assuming you are in Nepal rn ( You have mentioned being from Nepal ) it can also be due to some internet towers in there being damaged due to the protests or lakx of maintenance. But I believe the first reason is the more likelier cause of your high PL and Ping
