Yeah, unfortunately that’s what I’m hearing around here. 
Are you having disconnection issues as well? If so, is the Blizzard launcher also disconnecting (either at the same time or not)?
If so, that’s something that Bliz is investigating. There’s a thread that they are monitoring that you can find here. They have a series of steps to try to see if anything helps. If not, there’s a special log file they’d like you to email in for the engineers to look at as part of their investigation.
However, if you are only disconnecting from CoD (and not the launcher), unfortunately you’re at the mercy of what ever support Activision has.
