DDoS attacks come in three broad families: volumetric floods that saturate your pipe, protocol attacks that exhaust connection state, and application-layer floods that look like legitimate traffic. Each one exhausts a different resource, so each one needs a different defence, and no single layer stops all three. This guide maps the common attack forms to the resource they target and the mitigation that actually works against them, explains what an on-host firewall can and cannot stop, and ends with a practical incident-response runbook for when your server is under fire.

A Windows dedicated server gives you a whole physical machine running Windows Server directly on the hardware, but which version and edition should you run on it? Windows Server 2019, 2022, and 2025 sit at different points on the support timeline, and Standard versus Datacenter changes what you can do with virtualisation. This guide explains what a bare-metal Windows server actually is, when it beats a VPS or cloud instance, and how to pick a version and edition by workload, support window, and licensing, with a side-by-side comparison and links to the right server.

Ping is only part of what a player feels. A single round trip runs through input sampling, the last mile, transit and peering, a queue on the server, and the wait for the next simulation tick before the world reacts at all. This guide breaks down where felt delay actually comes from, how tick rate and netcode change the picture, why jitter and packet loss hurt more than a stable higher ping, and the one lever a host controls most: putting the server close to players on hardware that holds its tick rate.

Connecting multiple office sites or datacenters securely and efficiently is a critical challenge for modern businesses. Traditional VPN solutions like IPsec or OpenVPN can be complex to configure and maintain, especially in multi-site environments. WireGuard offers a lightweight, fast alternative that's easier to set up. VyOS 1.5 fully supports WireGuard, making it an excellent choice for organizations looking to interconnect multiple datacenters or sites. In this guide, we'll show you how to set up a site-to-site WireGuard tunnel on VyOS 1.5. We'll cover routing, firewall configuration, and best practices. By the end, your sites will be securely connected over the internet with traffic routed effectively between LANs.
