Bare Metal vs Cloud: Pricing the Same Server Both Ways
We priced one steady workload both ways in Frankfurt: a 24-core EPYC 9254 dedicated server at €449 a month against the closest AWS m7a instance, with storage, a one-year Savings Plan and internet egress added. The arithmetic is shown, including where the cloud honestly wins.

Server Under DDoS Attack? What to Do in the First Hour
A first-hour runbook for a Linux server under attack: how to rule out a bad deploy or a crawler, the commands that show which layer is failing, what SYN cookies, nftables and rate limits can fix, what only your provider can, and what to ask about null routing.

Multi-Region Dedicated Servers: Cities, Latency and Replication
A second region turns an outage into a failover and puts capacity near distant users, but the distance between cities sets hard rules for replication. Round-trip floors for ten city pairs, synchronous versus asynchronous, three designs that work, and what two or three regions cost.

Streaming Dedicated Server: Sizing the Port From Published Bit Rates
For video delivery, the port, not the processor, usually sets the budget. Apple's published bit-rate ladder turned into concurrent viewers per port, the three jobs a streaming server does, live versus on demand, and the signs that one server is no longer enough.

20Gbps Dedicated Server: Cost, Bonding and Bottlenecks
Twenty gigabits is where the details of delivery start to matter: one interface or two bonded links, disks that can keep up with 2.5 GB/s, and TCP windows that cap a single connection. What a 20Gbps port moves, what it costs on each build, and how to make sure you get all of it.

Rent a Dedicated Server: What the Monthly Price Covers
Renting a dedicated server bundles hardware, power, network and IP addresses into one monthly price. What that price covers and what it leaves out, how billing periods, notice and refunds really work, a worksheet for comparing rent with owning, and a checklist to run before you sign.

Frankfurt Dedicated Server: DE-CIX, Latency and Who It Suits
Frankfurt is Europe's centre of gravity for hosting: over 1,000 networks on DE-CIX Frankfurt and short distances to Germany, Austria, Switzerland and Central Europe. Distances against Amsterdam, the audiences Frankfurt serves badly, and every build you can order there.

1Gbps Unmetered Dedicated Server: What the Port Really Delivers
"1 Gbps unmetered" hides three questions: how much data the port can really move, whether the gigabit is yours or shared, and what the next step costs. The arithmetic for each, from TCP overhead to concurrent video streams to the price per terabyte at every Xeon port size.

Amsterdam Dedicated Server: Peering, Latency and Who It Suits
Amsterdam is often the first answer for European hosting, for measurable reasons: 853 networks on AMS-IX and short distances to London, the Benelux and southern Scandinavia. The numbers behind that, the audiences Amsterdam serves badly, and every build you can order there today.

Proxmox Dedicated Server: Sizing a Host to Replace VMware
VMware now licenses every physical core, with a 16-core minimum per CPU; Proxmox VE subscriptions are priced per socket. What that difference does on a 256-core host, how to size RAM and ZFS storage for a Proxmox host, and which dedicated builds fit which estate.

Self-Hosted DDoS Protection: Run Your Own Proxy or Buy a Managed One?
A proxy licence on your own dedicated server gives you unlimited domains, TLS keys on your own hardware and a cost that does not grow with traffic. It also makes you the operator. The real costs of both routes, and the one thing no self-hosted proxy can do alone.

100Gbps Dedicated Server: Who Needs One, and What It Takes to Fill It
A 100Gbps port moves 45 TB an hour. Who genuinely needs that, which server builds can carry it, what it costs per gigabit compared with slower ports, and the four bottlenecks, from the network card to packets per second, that stop most servers short of line rate.

How to Hide Your Origin IP Behind a DDoS Proxy, and Keep It Hidden
Attackers who find your server's real address skip the proxy and flood the origin directly. The eight places origin IPs leak, from DNS history to certificate logs to mail headers, how to test for each one, and the firewall rule that makes a leak survivable.

Xeon vs EPYC: Choosing a Dedicated Server by Workload, Not Core Count
A 2014 Xeon and a 2023 EPYC can both be the right answer. Eight real builds compared on the numbers that decide performance, from clock speed and memory bandwidth per core to I/O and delivery time, with a plain recommendation for each kind of workload.

WordPress DDoS Protection: What a Proxy Stops That a Plugin Can't
A security plugin runs on the server it is trying to protect, so by the time it blocks a request the damage is done. Which WordPress endpoints attackers actually hit, what has to sit in front of the site instead, and how to size a proxy plan from your own traffic.

Cheap Dedicated Server in Europe: What €129 a Month Actually Buys
The sticker price is the least useful number on a server listing. What the €129 entry build includes, the add-on lines that turn cheap hardware into an expensive invoice, and the workloads where a 2016-era Xeon is the wrong place to save money.

Shared Hosting to VPS: When the Upgrade Actually Pays Off
A well-tuned site on good shared hosting beats a badly configured VPS every time, so performance is the wrong reason to move. The five resource ceilings that are the right reason, the three that are not, and the maintenance cost that is on no price list.

EU Data Residency: What It Buys You, and What It Does Not
Our data stays in the EU is one of the most common sentences in European hosting procurement, and one of the least examined. What Chapter V of the GDPR actually restricts, the current adequacy list, and the five questions to put to a provider before ordering.

The New Server Security Checklist for Your First Hour on Fresh Metal
A freshly provisioned server is found by automated scanners within minutes of its IP going live. Six steps, about forty minutes, that remove most of the ways a server gets taken over — and an honest account of the three categories they do nothing about.

95th Percentile Bandwidth Billing, Explained With the Arithmetic
Two servers move the same 25.4 TB in a month. One is billed for 50 Mbps, the other for 900 Mbps, and neither invoice is wrong. How the five-minute samples work, where the 36-hour cliff sits, and how to tell which billing model fits the shape of your traffic.

Migrate a Server Without Downtime: The Runbook, and the New EU Rules
Zero downtime is a claim about your database, not your files. The runbook in the order the clock imposes — TTL two weeks out, two rsync passes, replication versus a read-only window — plus what Regulation (EU) 2023/2854 now obliges your outgoing provider to do.

Black Friday Hosting: The Capacity Plan That Starts in September
Black Friday falls on 27 November 2026, and almost every decision that matters has a lead time attached. A week-by-week plan with real dates, the platform version requirements to check first, and the two documentation traps that take stores down in November.

How Much Bandwidth Does a Server Need? Do the Arithmetic
Most websites never come close to saturating the cheapest port on the market. Six worked examples — from a brochure site to a 400 TB game patch — showing how to size monthly transfer and peak throughput, and which of the two ceilings your workload actually hits first.

Managed vs Unmanaged Server Hosting: Pricing the Hours, Not the Invoice
The managed versus unmanaged decision is usually framed as a budget question, and that framing is wrong in a specific way. Unmanaged is not cheaper; it is differently priced. The cost moves from an invoice to a calendar, and calendars are harder to read.
