Bracing for network catastrophe
About 16 years ago, I remember the Canadian president of a major computer firm giving me a tour of his company's pavilion at the ITU world exposition in Geneva. The president proudly told me that 100% of his firm's data network was riding on the network of the company I was working for. I told him that he should fire his head of communications.
I thought my boss was going to swallow his lit cigar.
My concern was network reliability. My boss was concerned about revenues.
That same year, at the CRTC's Construction Program Review (CPR) meetings, I expressed concern about decommissioning switching centres to the point that too much traffic was running through buildings that would become catastrophic single points of failure. We were told not to worry; there were fault tolerant processors, dual cable entrances. As the CRTC used to find in its conclusion of the CPRs, there was no evidence to find the telco plans unreasonable - a double negative by design.
After Friday night's network failure, ask the people in Newfoundland if they still share the same level of confidence in their telecom network. Ask them if too much of the province's communications needs runs through a single building. As the investigation into Friday's network failure proceeds, let's see if there is still no evidence that the construction plans were unreasonable.
On August 2, Sault Ste. Marie was completely isolated by a fibre cut. In both cases, 9-1-1 emergency services were knocked out of service. Newfoundland's emergency measures chief is calling for proof that this won't happen again.
As we mentioned in August, the current CRTC reporting regime, designed to protect competitors, may not sufficiently look after the interests of individual consumers. We wrote:
In August, we asked if razor thin margins in a competitive marketplace may be a contributing factor. Will income trusts add further pressure?
Will the CRTC take charge of leading an examination of the security of network architectures, or will emergency measures organizations lead the way?

We think that consumers would be well served if all Canadian service providers, wireline and wireless, were required to report service outages affecting a broad base of subscribers for more than 15 minutes.Do we have an easily accessible database of service affecting outages? Shouldn't we?
We would include broadband internet access service providers in that reporting as well, given the migration of some voice services to ride over broadband. Reliable connectivity for consumers will become a competitive supplier issue as access independent services take hold.
In an environment of government organizations looking at emergency preparedness, we may need to have an independent audit of how carriers are engineering their networks in a competitive environment.

Was it just 9 years ago that the Simcoe CO fire took out the vast majority of the BELL network? In those days, internet wasn't the mission critical service that it is today.
That being said, still I have a hard time convincing customers that they need to think about redundancy planning in their networks. Still customers have a hard time grasping carrier diversity concepts. Still carriers grapple with last mile diversity.
You may be very close to the truth with your theory that a lack of viable margin in some services is causing network decisions to be more economic in nature than they should be. Even if multiple carriers have connectivity to the same location, it doesn't mean that they have extra capacity in the event of a failure.
