So today i got on Overwatch and the ping was insanely high, and the ping was fine the day before, and changing servers doesnt fix the problem. Usually i get 150 ping on the NA server, and 30 ping on the EU server, but now i get 400+ ping on the NA server, and i get 300+ ping on the EU server. I dont know why, the ping is fine with other games except for Overwatch. Plz help
Hello F4kEAstraiT,
Have you also tried the steps we gathered in this support article? If you haven’t just yet, please follow them (basic and advanced) and see if they help you. 
If, however, you already tried them and you noticed no improvement whatsoever, please run a traceroute and a pathping test (EU region) during a problematic moment and post the results here - let’s see if they’ll give us a bit more information!
Thank you!
