I was one of the people that was the first to get Black Ops 4 when it was first released. In the beginning I have had zero issues connecting to the servers for Blackout. Just recently, within the last week or two connecting to the servers has been horrible. Sometimes I can get in and sometimes I cannot. Finding solo or quads matches and take a very long time or it cannot find a match and loops back out. I think as the game has become more popular the servers cannot handle the load.
I have zero problems playing Fortnite and Rainbow Six for online play. I have a $400 wireless router just for gameplay, 5ghz, and incredible fast internet. The problem isn’t on my end. FIX YOUR SERVERS AND STOP PUTTING THE EXCUSES ONTO US!!!!!!
