Networking is always a center of awesomeness in those companies. I've seen things like six (at least) layers of NAT for "extra security" or super fast fiber optics that are unused because someone left everything hanging off a backup cable line months ago and forgot. In the latter case it was discovered after they spent weeks tweaking QoS settings to make it go faster to no avail.
