The Internet has infiltrated every industry, every business, and
every business model.<br>
<br>
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.<br>
<br>
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.<br>

<p>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. <br>
</p>
<p>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. <br>
</p>
<p>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?<br>
