When you see two almost identical addresses in the browser bar – one with www at the beginning and the other without it – it feels like they are just cosmetic variations. In practice, that is usually how it works, but from a technical point of view, these are not the same entities at all.
Sometimes a website starts behaving as if it is under a heavy DDoS attack: pages open slowly, the API responds with delays, 502 or 503 errors appear in the logs, and web server processes suddenly start consuming much more memory. But at the same time, there is no huge stream of requests, the channel is not saturated, and the load may come from a small number of connections. This is how HTTP/2 Bomb works. It is a DoS attack on HTTP/2 – the protocol through which a website or application exchanges data with the server. The attacker sends a relatively small amount of data but forces the server to spend much more memory processing it. As a result, the web server or proxy may freeze, start using disk instead of RAM, restart processes, or stop serving regular users properly.
There are situations when a simple check of whether a domain is “available or not” is not enough. For example, a website suddenly goes down after a DNS change, a domain refuses to transfer to another registrar, the delegation period is coming to an end, or you urgently need to find out who actually services this name. Usually, in such cases, people open Whois, expecting to see the basics: the creation date, registrar, DNS servers and current statuses, but Whois often disappoints. The data is displayed chaotically, the format depends on the specific domain zone, and some information is hidden altogether. As a result, the output turns into a solid block of technical text, where a user without experience may struggle to quickly find the needed line. And for automation services, this lack of standards has long become a headache.
On the eve of Kyiv Day, the RX-NAME team congratulates Kyiv residents and everyone whose business, work, bold ideas and new projects are connected with the capital. We wish our city development, resilience, energy and even more great initiatives that make it modern and recognizable.
A website can rank well in Google for years, receive steady traffic, and gradually lose part of its audience even without any drop in rankings. This is currently one of the strangest situations in search. Everything seems to be working, there are no technical issues, SEO is being done, content is being published. But people are increasingly getting answers before they even open the website itself.
Not that long ago, most interaction with AI followed a pretty simple pattern: open a browser, type a request, get a response. But at some point it became noticeable that large companies had started moving in a slightly different direction. AI is gradually stopping being a separate service “somewhere in a tab”. It’s being built directly into the devices themselves.
At the end of April 2026, the Linux community started talking about a flaw in the algif_aead kernel module. The issue is local, but critical: an attacker with minimal privileges inside the system can escalate to root. In practice, this means losing control over the server. After obtaining root access, a third-party user can extract databases, configuration files, SSH keys, or completely rebuild the system for their own purposes. The situation became much more dangerous because ready-made instructions and exploitation tools appeared in public access almost at the same time as the vulnerability itself became known. Script kiddies and automated scanners usually start using things like this within the first days.
May 17 is marked on the calendar as two closely related occasions: World Telecommunication and Information Society Day and Internet Day. This date is tied to the year 1865, when the International Telecommunication Union was founded. Back then, rules for international telegraph communication were being developed. Later, Morse devices were replaced by telephone lines, then mobile communication, satellites, and fiber optics appeared. Now information can be transmitted across distances in milliseconds.
In conversations about hardware, the focus is usually shifted toward the processor. That is logical, but in practice performance depends not so much on raw computing power as on whether the system can keep “feeding” that processor with data fast enough. When RAM cannot keep up, an expensive multi-core chip simply sits idle waiting for the next portion of information.
Rebranding is often seen as a complete restart: a new name, a fresh logo, a different tone of communication, and a move to a new website. It seems logical to leave everything old in the past, but this rule does not work with a domain. An address that served as an entry point for years is not just a line in a browser, but the digital history of a business, and it should not be cut off in a single day.
