Uh, not exactly. There was diversity in this case, but there was also N+1 breaks. Outside of a few counties in the Bay Area, the rest of the country's telecommunication system was unaffected. So in that sense the system worked as designed.

Read the original DARPA papers, they were not about making sure grandma could still make a phone call.


For a good "man in the street" perspective of how the outage effected
things like a pharmacy's ability to fill subscriptions and a university
computer's ability to boot check out a couple of shows broadcast on KUSP
(Santa Cruz Public Radio) this morning:

Why didn't the "man in the street" pharmacy have its own backup plans?

Why didn't the pharmacy also have a COMCAST or RCN broadband connection for alternative Internet access besides AT&T or Verizon, a Citizens Band radio channel 9 for alternative emergency communications besides 9-1-1, a satellite phone for alternative communications besides local cell phones, and a Hughes VSAT dish for yet even more diversity? Why was the pharmacy relying on a single provider? Or do it the old-fashion way before computers and telecommunications; keep a backup paper file of their records so they could continue to fill prescriptions?

Why didn't the pharmacy have more self-diversity? Probably the usual reason, more diversity costs more. That may be the reason why hospitals have more diversity than neighborhood pharmacies; and emergency rooms have other ways to get medicine. Maintaining diversity and backups is probably also part of the reason why filling a prescription at a hospital is much more expensive than filling a prescription at your neighborhood pharmacy.

Likewise, why didn't grandma have her own pharmacy backup plan. Don't wait until the last minute to refill a critical presciption, have backup copies of prescriptions with her doctor, have an account with an alternative pharmacist in case her primary pharmacist isn't reachable, etc.

Readiness works better if everyone does their part, including grandma.

Next time it won't be AT&T, it will be Cox or Comcast or Qwest or Level 3 or Global Crossing or .... or .... or .... . It won't be vandalism, it will be an earthquake, backhoe, gas main explosion, operator error, ....

Everything fails sometimes.  What's your plan?
