Netcode Issues (Presumably)

2 days ago I randomly  had problems with connection. My friends connection was low and had crosses and they saw the same for me. I was for them on completely different parts of the circuit with a completely different delta. We all assumed it was a Netcode issue, because the latest Multiplayer session with a friend of mine, got us both kicked with the: "Check ea.com/unable-to-connect." message.
I have no idea how to fix it or if it's from my, my friends side or because of EA.
