Sledgehammer Games and Activision said before Advanced Warfare's launch that it would feature dedicated servers for all platforms, but it's using peer-to-peer connections, leading to weaker match stability.
The general response from Activision is, "We're aware of connectivity issues currently being experienced. They are under investigation. Stay tuned for updates."
We've reached out to Activision about which platforms are having the most issues, what's being done to correct them, and what the official status is on dedicated servers. We'll update this story the moment we know.
