Re: Ad driven WiFi or just beefing up clogged network
the DWDM stands for "dense wavelength division multiplexing". In Google's case, though, perhaps DWDM stands for "divide with diverse marketing" - meaning a divide and conquer strategy of providing free access, driven by Google's ad revenues, and effectively cutting traditional ISPs out of the loop (local or otherwise).

Google users have started to see something less than their usual sterling performance when visiting Google web sites. Maybe Google isn't trying to build a national WiFi network. Maybe they are just beefing up their infrastructure so that users continue to see the excellent response times they are used to.

P.S. In case anyone was wondering in "optical DWDM network" the DWDM stands for "dense wavelength division multiplexing". Here is a link for what that is:
»www.iec.org/online/tutorials/dwdm_test/
At its simplest, a dense wavelength division multiplexed (DWDM) system can be viewed as a parallel set of optical channels, each using a slightly different light wavelength, but all sharing a single transmission medium. This new technical solution can increase the capacity of existing networks without the need for expensive recabling and can significantly reduce the cost of network upgrades.
