The much worse problem is DNS. For big networks that pushes always the same two IPs (even without round-robin) it is a disaster. There are lags of servers, lags of network, dropped packets, useless overhead with EDNS and different packet sizes (timeouts and retransmitions) and above all, the practice by content providers and CDNs to use hundreds of changing in real time hostnames to implement load balancing and/or geoIP based assets loading. They use near zero TTLs which makes caching useless and dynamic sets.
Indian Airtel's network is a live example of that disaster. It is almost unusable, while they still actively promoting 3G and iPhones. ^_^
