Virginia Ping from 150 to 105

I’ve had a 105 ping virginia couple months ago now it’s constantly at 150. I didn’t change my network provider or anything, the ping suddenly went up by 45 and it stays there. With paid Ping boost 3rd party programs (such as Lagofast) i can put my ping on virginia from 150 to 105 again but this only gives me a 24h free trial and costs money. I would like for virginia to be 105 again.
