Don't sidestep, this is not the point.
People have been saying it's IPC since March, and even as recently as the 17th you guys had no IPC issues. Now your boss said it is IPC issues.
So, we want to know where the miscommunication came from,
[1] You guys only figured out IPC was an issue yesterday. After months of tweaking and having the best experts in the world work on your network 24x7 (again, as posted multiple times by the Social team)
[2] The Social team did not know about IPC issues. Which means the Social team was being "misdirected".
[3] The Social team was aware of the IPC issues, but weren't allowed to confirm it here.
It's one of these.
