How Let’s Encrypt Changed the Architecture of Security

How Let’s Encrypt made the internet safer

The emergence of Let’s Encrypt became one of the most important milestones in the history of internet security. Until 2015, obtaining an SSL or TLS certificate was a complex, expensive, and time-consuming process. Many website owners postponed switching to HTTPS because they had to navigate bureaucratic procedures, wait for certificate approval, and manually configure their servers. This created a paradox: the technology for protecting data existed, but access to it remained limited. Let’s Encrypt made security widespread, affordable, and automated — transforming not only the approach to encryption but also the architecture of the internet as a whole.

Why the Transition from HTTP to HTTPS Took 20 Years

The long journey from unencrypted connections to complete web traffic security

The transition of the internet from HTTP to HTTPS seems like an obvious step today, when secure connections have become the standard. However, this process stretched out for nearly two decades. Although HTTPS has existed since the late 1990s, its widespread adoption began only after 2015. The reasons for this delay lie in technical limitations, low availability of certificates, reluctance of website owners to change infrastructure, and even psychological factors. To understand why the entire world took so long to switch to a secure protocol, it’s important to look at the history, technologies, and context of internet development.

In Servers

Two servers: one marked with a speed symbol, the other with a cloud icon, highlighting the difference between VPS types.
Difference in performance of different types of VPS

Virtual servers have long been the foundation of modern online projects. They provide flexibility, high performance, and the ability to scale without significant costs. However, a new class of solutions has emerged on the market — Turbo VPS, which immediately draws attention with its increased speed and stability. At first glance, it may seem like just a marketing name for a regular VPS, but in practice, the difference between them is substantial. To understand why Turbo VPS works faster and more consistently, it’s important to examine which technologies deliver this performance boost and what the user gains in real-world operation.

How Backup Frequency Affects the Risks of Data Loss

How the rarity or frequency of backups determines the amount of potential loss after a failure

Backup, or data copying, is the process of creating copies of information that can be restored in case of a failure, error, or cyberattack. Although the idea itself seems simple, it is the frequency of creating backups that determines how serious the consequences of data loss may be. Some companies make backups once a day, others every hour, and some use complex automated scenarios. But regardless of business size, it is the regularity of saving copies that determines how much information you risk losing in case of an incident. Backup frequency directly affects the so-called recovery point, or RPO, which shows the amount of time for which data may be lost without critically affecting system operation.

How group chats in ChatGPT work and why they are needed

A group of people at laptops are chatting and discussing ideas, the ChatGPT logo is displayed on the screen above them in the form of a dialog in the clouds.
Collaboration accelerates when AI becomes part of team interactions

Group chats in ChatGPT have become one of the most notable new capabilities of artificial intelligence. If earlier interaction with the model happened in a “user — AI” format, now several people can join the dialogue simultaneously. This changes not only the communication format but also the very logic of interaction between people and a digital assistant. A group chat works as a space where artificial intelligence participates in team discussions, helps coordinate work, generates ideas, and reduces the workload on participants. To understand why this matters, it is worth examining how such chats function and in which situations they bring the greatest value.

What would happen if all Google servers were shut down for 60 seconds

Panicked employees sit in front of laptops against the backdrop of Google's server racks, which simultaneously went down.
The consequences of a brief but global outage of Google’s infrastructure

It is almost impossible to imagine the modern internet without Google. Search, Maps, Gmail, YouTube, Android, advertising, DNS servers, cloud infrastructure — all of this forms a massive ecosystem that operates quietly yet permeates almost every digital process. That is why the idea that all Google servers could simultaneously go offline even for one minute seems unrealistic. However, such a hypothetical scenario helps us better understand how the internet works and how significant the influence of a single tech corporation truly is. So what would happen during these sixty seconds?

Why a VPN Does Not Guarantee Privacy When You Use Mobile Internet

VPN privacy limitations when using mobile internet

A VPN has long become a tool that most users perceive as a universal means of protecting privacy. It creates an encrypted tunnel between your device and the VPN provider’s server, hiding your IP address and making data interception more difficult. However, when it comes to mobile internet, this mechanism does not work as flawlessly as it may seem. Even with the best VPNs, the user does not always receive full privacy, and the mobile operator still retains a significant amount of information about your activity. To understand why this happens, you need to understand how mobile internet works, what data the operator has, and what limitations the VPN itself has.

How power outages weaken cyber security of systems and data

Blackouts have stopped being just an issue of comfort or household inconvenience — today they directly affect digital security. When the power goes out, we think about charging our smartphones or keeping the internet running, but we don’t always consider that power disruptions create real threats to information systems. At a time when business, government services and personal data form the foundation of the digital economy, electricity has become a new key element of cyber defense.

How Artificial Intelligence Learned to Break CAPTCHAs and What Website Owners Should Do

The robot shows the person a recognized captcha, and the site owner holds his head in concern.
Captcha no longer stops AI

CAPTCHA has long been considered one of the simplest and most reliable ways to protect websites from bots. It required the user to perform an action that automated programs supposedly could not repeat: recognize distorted characters, select images with bicycles, or mark all traffic lights. But the era of artificial intelligence has changed the rules of the game. What seemed impossible for a computer ten years ago is now performed by algorithms faster and more accurately than humans. Website owners are now facing a reality where the familiar CAPTCHA no longer guarantees protection.

The state as a key investor in strategic AI infrastructure

Artificial intelligence has ceased to be a laboratory experiment and has become the foundation of a new economy. If just a few years ago AI investments were associated mostly with private companies, today governments have actively joined the race. The USA, the EU, China, Japan, and the United Arab Emirates are competing to build the most powerful data centers, purchase thousands of GPUs, develop their own models, and even form state-level alliances with corporations. The amount of investment is no longer counted in billions — but in trillions of dollars.
