We have recently been rolling out a new ERP system that is centralized at a new data center. This makes our WAN connection from our facilities to the data center critical. We had been receiving multiple reports of strange lock ups and connection disconnects that were assumed to be issues with our new ERP system servers. After looking at the NetFlow graphs during the issue time frames, I found multiple short (3-5) minute WAN outages. We were able to isolate the problem very quickly to be a WAN provider issue vs. spending hours troubleshooting LAN or server issues.
