Consider this…
Sometimes you are responsible for fielding the calls and explaining problems
that occur on systems that aren’t entirely within your control.
A business class ISP, for example, would have a hard time proactively fixing
all of their customer’s DNS resolvers and clients. Nonetheless, you can be
assured that their call center will get the calls when the behavior of DNS
changes in a way that negatively impacts some fraction of those clients.
In my estimation, the most likely impact of this event will be on the
enterprise, not the ISP or residential communities.
The ISP community is either aware of and/or dealt with it in the normal course
of business or they have had their head so deep in the sand that I don’t have
much sympathy for what happens to them.
The residential end user doesn’t run name servers for the most part, so,
unlikely to be much impact there. The ones that do (such as myself) are likely
technical enough and likely sufficiently involved in the ISP community to have
heard about this issue and taken appropriate action.
In my experience, enterprise IT, OTOH, is widely variable in its attentiveness
to changes on the internet until after they have occurred. Network focused
enterprises (e.g. Akamai, DropBox, etc.) are unlikely to be impacted. Other
kinds of enterprises for whom the internet is more of a utility than a core
function, OTOH, may have less awareness ahead of time (e.g. Chevron, GM, your
local dive shop, the bodega on the corner, etc.).
The larger enterprises probably have someone paying some attention. I suspect
most of the casualties in this event will be in the Small to Medium business
community.
