I'm trying to figure out whether this is a known issue with Plutonium or if something is wrong on my side.

What's happening

I'm playing Black Ops 2 on Plutonium. In the morning, when there were only around 300 players online, everything worked perfectly and I had no disconnects.

In the evening, when the player count goes above 1,000, I can usually play for about 5–10 minutes on a server and then the following happens:

Everyone on the server suddenly starts lagging.
The ping jumps to around 999 ms.
We get "Connection Interrupted" / "Lost Connection."
Eventually everyone gets disconnected from the server.

The important part is that this does not happen on just one server. I switch to a completely different server, and after a few minutes the exact same thing happens there as well.

That's why I'm wondering if there is some general Plutonium or server-related issue, especially during peak hours when more players are online.

Has anyone else experienced this recently, or does anyone know what could be causing it?
