High Latency

Good Evening
A few days ago I come with the problem that my ping is not lower than 130, my ping normally is 110-90 sometimes reaches up to 85 ... In short, already this that my ping is above normal had occurred to me more or less than 1 year and a half, I wanted to know if you have any suggestions (and restart the modem, router, change the LAN cables, restart the router to its state of manufacture ....) (Nothing works) Therefore I think the problem is on their servers, if I can help as soon as possible I would appreciate it.

Thanks...
