Energy is the invisible “fuel” of the modern internet. Everything we see online — websites, online stores, streaming services, or cloud storage — runs thanks to data centers that continuously power hundreds of thousands of servers. But behind stability, speed, and reliability lies a very real number measured in kilowatt-hours, and it directly determines the cost of your hosting.
September 2025 became a painful lesson for the entire IT industry. In South Korea, a fire at the headquarters of the National Information Resources Service destroyed the government cloud storage system that had been used for seven years by hundreds of public institutions. As a result, more than 120,000 civil servants lost their work files, and the total amount of destroyed data reached a staggering 858 terabytes. This was not just a technical disaster — it was a vivid demonstration of how dangerous it can be to store everything in one place, even if that place is a “government cloud.”
When a business or personal project outgrows the capabilities of shared hosting, the question of renting a VPS server arises. A VPS (Virtual Private Server) is a virtual server with dedicated resources that works independently from other clients on the same hardware. But where is it better to rent such a server — in Ukraine or abroad?
The choice depends on the tasks and priorities of the project owner. In this article, we’ll look at when a VPS in Ukraine becomes the best solution and in which cases foreign data centers are worth considering.
A few years ago, it became clear that IPv4 address space was no longer sufficient for the growing needs of businesses. For companies that operate their own servers or rent resources in data centers, this meant limitations in scaling infrastructure and connecting new clients. IPv6 became the logical next step: it provides an almost unlimited address space, simplifies server network management, and ensures modern security mechanisms. Thanks to this, company servers can seamlessly grow along with the business, maintaining stability and opening new opportunities for development.
The internet is changing rapidly, and with it, the sophistication of scammers is also growing. By 2025, phishing is no longer just primitive emails with mistakes — it has become a whole “industry” with its own support services and even phishing-as-a-service. Fake websites use deep learning to mimic the style of real websites and employee communication, while millions of phishing kits are available on the black market. For users, it is crucial to know how to tell a fake from the original.
Today’s hosting industry offers a wide range of solutions for businesses and personal projects — from regular shared hosting to virtual private servers (VPS) and dedicated servers. However, there are many myths and stereotypes surrounding these services that prevent users from choosing the best option. In this article, we’ll look at the most common misconceptions about VPS and dedicated servers, explain where they are used, and help you better understand the benefits of these solutions.
When we register on social networks, email services, or online banking websites, account protection often comes down to just a password. However, most users still rely on simple combinations that attackers can crack within seconds. Ukrainian cybersecurity experts repeatedly note that in mass password leaks, the same primitive keys appear again and again — such as “123456,” “qwerty,” or “password.” Most of these passwords are guessed by automated hacking tools in less than a second. To reduce risks, it’s important to know which combinations to avoid, how to create strong unique access keys, and why it’s safer to enter data only on websites with encrypted connections.
Modern data centers store valuable data and support online services, making physical security just as important as digital protection. Even the most advanced cybersecurity systems are powerless if an intruder can access the server room or if a fire damages the equipment. In high-class facilities like Tier III data centers, physical protection is a top priority—since uptime and data safety directly depend on it.
Less than a month remains until Microsoft officially ends support for Windows 10. On October 14, 2025, this popular operating system will receive its last security update, after which no new patches or fixes will be released. In other words, Windows 10 officially moves into the category of legacy products. In this article on Server.UA, we explain what the end of Windows 10 support means for everyday users, why Microsoft is taking this step, and recall the interesting historical context behind this decision.
An effective website is not just about good design and fast hosting. It also means:
If your website is hosted on a VPS or dedicated server, you have maximum control: from connecting external services to setting up automated tasks. In this article, we’ll walk you through:
