MW and Cold War no longer playable

Just before Cold War came out there was an update for MW. I have been playing this non stop since it came out and now I get disconnected from the servers every time I try to play. Cold War came out and I played it up to level 22 then there was a small update and bang same issue. I can’t play either game now and I have tried everything. Where is the issue Blizzard or Activision and can you guys work together to fix it? Reading forums this is not isolated.
