How to prepare a VPS for an operating system update

Preparing for an update is no less important than the update itself.

Updating the operating system on a VPS is often perceived as a routine technical procedure that can be performed between other tasks. In reality, it is one of the most critical stages in the life of a server. A VPS is usually used for specific business or infrastructure purposes: hosting websites, storing data, running services, or supporting internal systems. During an update, key system components are modified, and these components directly affect the stability and security of the entire platform. Without proper preparation, even a standard update can result in downtime, loss of access to services, or the need for urgent system recovery.

Why a VPS Stops Responding After Several Days Without a Reboot

By

On February 5, 2026

In Servers

A server with an error warning, a reboot process, and a recovered server with a stable state and active indicators.
Regular updates and restarts return the server to stable operation

Many website and online service owners notice a similar pattern: immediately after launch or a reboot, a VPS works fast and without issues, but after a few days the server starts to slow down, takes longer to respond to requests, or becomes completely unavailable. At first glance, it may seem like the problem appears suddenly, but in reality it builds up gradually. A virtual server is a living system where processes continuously consume resources, and if those resources are not released correctly, overall stability decreases over time.

When Increasing the Number of CPU Cores Does Not Improve Performance

By

On February 5, 2026

In Servers

A user at a computer waiting to download, next to a server with many processor cores, showing the lack of performance gain from their number.
More cores do not guarantee faster server performance

When choosing a VPS or a dedicated server, many users first look at the number of CPU cores. The logic seems simple: more cores mean higher performance and faster operation of the project. In practice, this rule does not always work. In many cases, increasing the number of cores does not deliver the expected effect and sometimes does not affect the actual speed of a website or service at all. To make the right server choice, it is important to understand how the processor is used under different types of workloads.

What happens to a VPS when it runs out of RAM

RAM shortage as a critical moment for stable server operation

Random access memory, or RAM, is the resource where a server stores data that programs need to operate “right now.” This includes website code, databases, cache, operating system processes, and system services. Unlike disk storage, RAM works very fast but has a limited capacity. On a VPS, the amount of RAM is fixed by the tariff plan, and the server cannot automatically use more memory than it has been allocated. As a result, the stability of a VPS directly depends on whether there is enough RAM to handle the current load.

What Is an API and Why It Exists in Almost Every Service

API as a universal way of interaction between different parts of a service

API stands for Application Programming Interface, which is a software interface for interaction between different systems. Simply put, an API is a set of clear rules that allow one program to communicate with another, send a request, and receive a response. End users usually do not see APIs and rarely think about their existence, yet they use them constantly. Logging in with Google, paying by card on a website, displaying the weather, exchange rates, or delivery status — all of this works thanks to APIs.

How Background Processes Consume VPS Resources

Impact of internal system processes on VPS load

VPS is often perceived as a “clean” server where all resources are available only to a specific website or application. The user expects that if nothing unnecessary is running, the CPU, memory, and disk will be used minimally. In reality, even in a state of relative idle, a server is never completely empty. Dozens of processes constantly run in the background, invisible at first glance, but it is precisely they that gradually consume VPS resources.

Why IP Reputation Is Crucial for VPS

IP reputation directly affects the stability and trust of a VPS

When a website, mail server, or API runs on a VPS, it receives its own IP address — a unique numerical identifier on the network. For internet services, this address has its own reputation, similar to a company’s business reputation. IP reputation is formed based on the server’s behavior: what requests it sends, which services run on it, and whether spam, phishing, or other suspicious activity is detected from it. A poor IP reputation can result in emails not reaching recipients, websites being blocked by browsers, and external services refusing to work with it.

Is “Fail-Proof” Hosting Possible and Why 100% Uptime Is a Myth

By

On December 9, 2025

In Servers

A worried user thinks about 100% uptime and possible server failure.
100% uptime is unattainable even for the most stable servers

In today’s digital environment, every business wants to be sure that its website or application is always available. Users do not tolerate delays, and companies understand that even a few minutes of downtime can lead to financial losses, reduced trust, or indexing issues in search engines. That is why VPS and dedicated server services often highlight uptime — the percentage of time the infrastructure operates without interruption. However, in real engineering, an absolute 100% uptime is unattainable. Even if the servers are expensive, the data center is certified, and the network is fully redundant, physical and organizational limitations still exist. To understand why “fail-proof” hosting is more of a marketing term, it is important to examine how VPS and dedicated servers actually work.

How a Hypervisor Divides a Physical Server into VPS

By

On November 7, 2025

In Servers

The physical server is divided into several independent VPSs.
Partitioning hardware resources into separate virtual environments

Not so long ago, to launch a website or an online service, it was necessary to rent or purchase a whole physical server. This is expensive, difficult to administer, and comes with excessive capacity that often remains unused. The situation changed with the appearance of virtualization — a technology that allows creating several independent virtual servers on a single physical server. Each of them operates as if it has its own processor, memory, disk space, and operating system. The key element of this process is the hypervisor. It acts as a “conductor” that controls the distribution of resources and ensures the stable operation of each VPS.

10 Tips for Choosing the Right Server Configuration for a Startup

A system administrator is configuring a server at a laptop, with a cloud, servers, and a checklist of parameters shown nearby.
Optimal server configuration is the foundation of a successful startup

Launching a startup is always a mix of ideas, speed, and technology. At the early stage, it’s not enough to build a product — you also need to ensure its stability. The server is the foundation of any online project, and its configuration determines whether your website can handle the first wave of users, how fast pages will load, and how easily the system can scale in the future. A wrong choice can cost time, money, and customer trust — so it’s worth approaching this decision carefully.
