Ping spikes since yesterday

I checked my connection history data here in EA, all my matches had a connection quality of over 90+. In the last 4 games it's under 20... During these matches it shows the "unstable connection little warning and the ping speeds that go from 30 to over 200. I also checked my connection in playstation and it's great. So if it's not my fault can you PLEASE explain and fix it?
