I think there's a bit of a misunderstanding of what I'm trying to say here. We have dual private lines from two Tier I providers. These interconnect all major hospitals and our data centers. We also have a third metro connection that connects things regionally. We have DIA on top of that. I think people are vastly underestimating just how much $aaS there is within the medical field. TeleDoc, translation services, remote radiologists, the way prescriptions get filled, how staffing works, third party providers basically hoteling within our facilities, critical staff VPNed in because the government has locked things down, etc. Then there's things that we don't use but I'm sure other providers do, GoToMeeting, O365, VaaS, etc.There's no practical way to engineer your WAN to facilitate dozens of connections to these services.

This extends beyond just hospitals as well. Fire departments, police departments, water treatment etc. Regardless of whether or not those entities planned well(I think we did), the government should and will step in if critical services are degraded. And for what it's worth, Stephen, I know how things are built within the ISP world. I spent four years there. That doesn't change the fact that we're possibly heading into uncharted waters when it comes to utilization and the impactthat will have on $aaS products that are interwoven into every single vertical, including entities that fall under TSP, critical national security and emergency preparedness functions, including those areas related to safety, maintenance of law and order, and public health.It's easy for all you guys to sit here and armchair quarterback other people's planning but when things really start to degrade, all bets are off.If you don't believe that, just look at the news. States are literally shutting down private businesses (restaurants, bars, night clubs, private schools) and banning people from associating in groups of larger than 50.

The Internet has infiltrated every industry, every business, and every business model.

While it's a great way to connect a lot of people and things at scale for the lowest cost possible, there are some industries that still require a certain caliber of reliability that the public Internet may not be best suited to provide.

In your case, I am not sure I have an answer for you, unfortunately. The public Internet is what it is, mostly best-effort. Your applications and use-cases certainly deserve better than that. I'm not sure how to achieve that as your industry shoves more and more activity into the public Internet domain, for one reason or another.

Mark.


In theory best-effort Internet is seen as only part of a broader Internet model including open peering and so on. The idea for open Internet is it offers a form of digital herd immunity (to coin a current phrase being misused by UK Government circles in recent days)  that offers a level of shared redundancy of spare capacity so that issues can be taken out of route until fixed but the edge still maintains high quality connectivity.  In one sense the Internet model provides an informal community insurance across the provider / access sector. Although of course the legacy telco regulated protected infrastructure has remained a nub of resistance to open anything.

Some short term financial optimisations between networks may turn out to be counter productive across time and "events". Which begs a question whether the winner takes all model that has emerged can live with a plural supply chain of network infrastructures.

I suspect the concentration over recent years has created greater fragility for all of us judging comments in this thread and elsewhere. Can we survive covid 19 and maintain selfish networks over open ones?
