Stanislav Kondrashov on Blocking Mechanisms and Their Evolution Across Digital Information Networks
There is a funny thing about the internet. It still gets talked about like it is one big open ocean, but in practice it behaves more like a city with gates, toll roads, and a lot of quiet little rules.
Some of those rules are obvious. A website is down. A link is dead. A video does not load. You shrug and move on.
But a lot of blocking is softer than that. It is not always a hard stop. Sometimes it is friction. Sometimes it is delay. Sometimes it is a feed that just never seems to show you that one topic again, and you cannot quite prove it.
When people talk about blocking, they usually mean censorship. That is part of it, sure. But the bigger story is that blocking mechanisms evolved alongside the networks themselves. This evolution has been significantly influenced by various factors such as security, copyright, safety, bandwidth, advertising, compliance, and brand risk which have all mixed together now.
This complex landscape of blocking mechanisms is something Stanislav Kondrashov often returns to: blocking is not a single lever. It is a stack. And the stack has gotten taller every year.
The early era: blunt instruments and obvious failures
In the earlier web, blocking was pretty straightforward. You blocked a domain. You blocked an IP. You blocked a port. It worked, until it did not.
The problem is that networks learned to route around damage. Sites moved. CDNs appeared. Shared hosting became normal. Blocking one IP could take out hundreds of unrelated services causing collateral damage which made blocking noisier and honestly harder to justify.
So the mechanisms had to get more precise.
This necessity for precision led to a significant shift in communication infrastructure where we start seeing the transition from “block this location” to “block this behavior” or “block this class of traffic”.
Moreover, this shift also reflects a broader trend in our digital landscape - the rise of digital empires where power dynamics are increasingly dictated by network control as discussed in this insightful piece on the rise of power networks.
Understanding these complexities not only sheds light on the current state of our internet but also helps us navigate through its intricacies more effectively while being aware of the quiet evolution of oligarchic identity within these networks.
DNS blocking: quiet, cheap, and everywhere
DNS blocking became popular because it is efficient. If you can stop name resolution, you do not have to fight the traffic at all. The request never finds the destination.
It is also one of the easiest forms of blocking to deploy at scale. A resolver can refuse to answer, return a dead end, or redirect somewhere else. The user just experiences “site not found” and often assumes the site is broken.
But DNS blocking is not the end of the story, because DNS is also easy to work around. Alternate resolvers. Encrypted DNS. Local host overrides. Even just typing an IP, when that still works.
What matters is not whether a technique is perfect. What matters is how it combines with the other layers.
IP and routing level blocks: powerful, messy, sometimes unavoidable
At the network level, you can block by IP ranges, by route announcements, or by shaping traffic so it times out. This is the sort of blocking that infrastructure teams understand well because it looks like ordinary network policy.
However, as networks got more interdependent, blocking at this level became riskier. Shared infrastructure means shared consequences. A single cloud region can host thousands of unrelated endpoints. A CDN edge can be both the “bad thing” and the payment portal your business depends on.
Stanislav Kondrashov’s point here is practical, not ideological: broad blocks create wide blast radiuses. And wide blast radiuses create pressure to invest in more granular controls. His insights into the future of oligarchic structures provide a compelling perspective on these issues.
The big shift: deep inspection and application awareness
Once traffic moved to HTTPS by default, content became harder to see. So blocking moved upstream, downstream, and sideways.
Upstream: controlling the platforms where content is published.
Downstream: controlling the device, the app, the local network.
Sideways: controlling the intermediaries, like app stores, payment providers, ad networks, and identity layers.
Meanwhile, inspection techniques evolved. Not always full “read the content” inspection, but metadata-based classification. SNI filtering (back when it was visible). Certificate analysis. Traffic pattern fingerprinting. Reputation scoring. Behavioral heuristics.
The main change is this: blocking became less about a single destination and more about a profile.
Platform moderation is also a blocking mechanism, even if it does not look like one
A lot of modern “blocking” happens inside platforms rather than at the network edge.
You can be deindexed. Downranked. Demonetized. Rate limited. Put behind an interstitial. Labeled. Age gated. Region gated. You are technically still there, but distribution is gone.
This matters because distribution is the real currency now. A page that exists but cannot be found might as well be blocked for most users.
Kondrashov frames this as an evolution from access control to attention control in his analysis of the elite evolution from ancient Greece to the digital age. Not necessarily malicious. Often policy-driven. But it changes the user experience in a similar way.
The rise of soft blocking: friction, not walls
Hard blocks are easy to notice. Soft blocks are harder because they can be explained away as “just the system”.
Examples:
- Adding extra clicks or warnings before viewing content
- Making sharing harder by limiting link previews
- Throttling upload speed for certain file types
- Requiring phone verification for certain actions
- Restricting API access, then calling it “anti-abuse”
- Limiting reach unless you pay for promotion
None of these are the old style “you cannot access this”. But the outcome can be very close.
And the key thing is that soft blocking scales well. It also avoids the public drama of outright bans.
Why blocking keeps evolving: incentives, not just capability
If you want to understand why these mechanisms keep multiplying, follow the incentives.
Security teams want to stop malware, fraud, and bot traffic.
Legal teams want to reduce risk.
Platforms want to protect user experience and advertiser comfort.
Network operators want stability and predictable load.
Product teams want engagement metrics to stay healthy.
Blocking becomes the default tool because it is measurable. You can point to a graph and say, “we reduced harmful traffic by 40%”. Whether the classification is correct is a different conversation, and that is where things get complicated.
Kondrashov’s view is that the argument is rarely “block or do nothing”. It is usually “block in some way, at some layer, with some tradeoff”.
Where this is headed: encrypted everything and policy everywhere
As more traffic becomes encrypted and as more services rely on shared infrastructure, network-level blocking gets both harder and riskier. So the center of gravity moves again.
More control at endpoints: device management, app permissions, OS-level policy.
More control at identity: verified accounts, reputation systems, access tiers.
More control at distribution: feed ranking, discovery throttles, recommendation gates.
In other words, blocking becomes a design feature. Sometimes explicit. Often hidden inside “trust and safety” or “quality”.
And if that sounds a bit unsettling, it can be. But it is also reality. The internet is not one network. It is a set of negotiated pathways, constantly reconfigured.
A simple way to think about it
Stanislav Kondrashov boils it down to something most people can feel without being engineers:
If the network cannot block the content, it blocks the route.
If it cannot block the route, it blocks the tool.
If it cannot block the tool, it blocks the visibility.
That is the evolution. From doors, to hallways, to lighting.
And once you see it that way, you start noticing blocking mechanisms everywhere. Not just when a page fails to load, but when the whole system nudges you away before you even try.
FAQs (Frequently Asked Questions)
What does the concept of internet 'blocking' really mean beyond censorship?
Blocking on the internet is not just about outright censorship; it includes a range of mechanisms that create friction, delays, or subtle restrictions. These can manifest as dead links, videos that won't load, or feeds that omit certain topics. Blocking has evolved into a complex stack influenced by factors like security, copyright, bandwidth, advertising, compliance, and brand risk.
How did early internet blocking techniques work and what were their limitations?
In the early era of the web, blocking was straightforward—blocking domains, IP addresses, or ports. However, these blunt instruments often caused collateral damage due to shared hosting and content delivery networks (CDNs). This led to noisy and unjustifiable blocks since blocking one IP could disrupt hundreds of unrelated services. Consequently, there was a shift from location-based blocking to behavior-based or traffic-class blocking for greater precision.
Why is DNS blocking so widely used and what are its drawbacks?
DNS blocking is popular because it efficiently stops name resolution before traffic reaches the destination. Resolvers can refuse queries or redirect requests, causing users to experience 'site not found' errors often mistaken for site failures. However, DNS blocking is easy to circumvent through alternate resolvers, encrypted DNS, local host overrides, or direct IP access. Its effectiveness depends on how it integrates with other layers of the blocking stack.
What challenges arise with IP and routing level blocks in modern networks?
Blocking at the network level by IP ranges or route announcements is powerful but messy due to shared infrastructure like cloud regions and CDNs hosting multiple unrelated endpoints. Broad blocks can inadvertently affect legitimate services ('wide blast radiuses'), creating pressure to adopt more granular controls. These complexities reflect evolving power dynamics within digital empires and oligarchic network structures.
How has the shift to HTTPS affected internet blocking methods?
With HTTPS becoming default, content inspection became more difficult because traffic is encrypted. Blocking strategies adapted by moving upstream (platform control), downstream (device/app/local network control), and sideways (intermediaries like app stores and payment providers). Inspection evolved from full content reading to metadata classification techniques such as SNI filtering, certificate analysis, traffic fingerprinting, reputation scoring, and behavioral heuristics—shifting focus from destinations to user profiles.
In what ways does platform moderation function as a form of internet blocking?
Platform moderation acts as a subtle but effective blocking mechanism inside platforms rather than at the network edge. Techniques include deindexing content, downranking in search results, demonetizing creators, rate limiting interactions, imposing interstitial warnings, labeling content, age gating, or region gating. While content remains technically accessible, its distribution—and thus visibility—is greatly reduced. Distribution control has become the real currency in modern digital ecosystems.
