Cloudflare is one of the largest internet service providers in the world. Many websites rely on Cloudflare because it offers three major advantages:
🚀 Faster loading times thanks to servers distributed around the globe
🛡️ Protection against attacks, such as DDoS
🔁 Stable availability, even under heavy traffic
Because Cloudflare delivers these features efficiently and at a good price, an enormous number of websites depend on it. But that popularity also creates a risk: When Cloudflare goes down, many sites go down with it.
🧩 Why self-hosted servers are often less affected
If you host your website or application on your own server, you’re far less dependent on big platforms like Cloudflare. That means:
🔐 More control over your own security
With simple measures such as:
🔑 SSH keys instead of simple passwords
🚫 Firewalls to block unwanted access
🛡️ Fail2Ban, which automatically blocks repeated attack attempts
you can secure your server very effectively—without relying on external security services.
🕹️ More control & more reliability
I host my servers at Hetzner in Falkenstein, Germany 🇩🇪 — and during the Cloudflare outage, not a single second of downtime occurred. Everything continued to run perfectly.
To me, this is a perfect example of digital sovereignty in Germany: Not depending on large U.S. providers, but maintaining your own stable, local infrastructure.
⚠️ Of course, nothing is 100% risk-free
✨ Running your own server doesn’t mean nothing can ever go wrong. Self-hosted servers can also experience:
outages 🛑
overload 📈
network or power issues 🔌
But the key difference is: you have the responsibility— and the control.
🎯 Conclusion
The Cloudflare outage shows how vulnerable large, centralized internet services can be. If you host your servers yourself—such as at Hetzner in Germany—and secure them properly, you often end up with a more stable and sovereign solution. 🧭
In modern IT security, strong passwords and firewalls are just part of the story. Equally important is how sensitive information is shared. To meet this need, I am introducing a new service: PrivateBin – a fully encrypted, secure platform for sharing files and messages.
🔒 What is PrivateBin?
PrivateBin is a client-side encrypted paste and file-sharing service designed to securely exchange confidential information. Unlike traditional upload or paste platforms, PrivateBin performs encryption directly in your browserbefore any data reaches the server.
This means:
The server cannot read the contents
Encryption keys never leave the client
Only encrypted data blobs are stored
Decryption is only possible with the key embedded in the generated link
In other words, PrivateBin operates as a zero-knowledge service. As the service provider, I technically cannot access or view any uploaded content.
📦 What Benefits Does My PrivateBin Service Offer?
To ensure the highest level of security and usability, the deployed system has been enhanced with several important features:
✔ Secure Transmission
All data is encrypted client-side and transmitted via HTTPS.
✔ Protected Storage
Only encrypted data is stored on the infrastructure — completely unreadable to anyone.
✔ File Uploads up to 50 MB
Ideal for sharing documents, diagnostic logs, confidential information, or larger technical files.
✔ Limited Retention
Files and messages are automatically deleted after 4 weeks — permanently and irreversibly.
✔ Optional Password Protection
Each paste or file can be secured with an additional password for extra peace of mind.
✔ No Registration Required
The service is available instantly — no accounts, no personal data collection, no tracking.
📁 Use Cases for Businesses & Teams
Securely sharing credentials
Exchanging confidential client documents
Sending system logs or diagnostic outputs
GDPR-compliant information transfer
Project communication without email risks
Safe data exchange with external service providers
Temporary sharing of sensitive files
PrivateBin is especially useful whenever traditional email or messaging tools are too risky or not appropriate.
🔧 Why I Provide This Service
As an IT service provider, I frequently encounter situations where clients need to share confidential information with me or within their teams. Sending such content through insecure platforms — or via plain-text email — introduces unnecessary security risks.
By offering PrivateBin, I provide a secure, controlled, and modern method for exchanging sensitive data without requiring any additional software installations.
🚀 Available Now
The service is available immediately and can be used at any time. If needed, I can also deploy PrivateBin as a dedicated in-house solution, customized with your company’s branding, policies, and security requirements.
🔧 I Run My Own Push Service – Without Google or Apple
As an IT service provider, I value privacy, control, and independence. Most apps on Android or iOS rely on the major cloud services from Google (Firebase Cloud Messaging) or Apple (APNS) for their notifications. These systems are convenient—but they also mean that every notification travels through external servers.
I wanted to do things differently: privacy-friendly, transparent, and fully under my own control. That’s why I’ve set up my own push service based on NTFY.
🌐 What Is NTFY?
🧠 NTFY is a free and open-source software solution that sends push notifications over the internet—without a central provider, simply via HTTPS. You can think of it like a small private mail carrier for your apps: Instead of Google or Apple forwarding your messages, your own server takes care of it.
📲 This becomes especially powerful when combined with the open standard UnifiedPush. UnifiedPush ensures that apps on your smartphone are no longer dependent on Google services to receive messages. Instead, the apps register with your own push server—in my case:
This allows notifications (for example from messengers or email apps) to work without a Google account or Play Services.
🔒 Privacy and Security Come First
🛡️ The big advantage: All data stays on my server.
That means:
No connection to Google, Apple, or any other cloud provider
No data sharing or analysis by third parties
Full control over retention periods, logs, and access rights
📊 Push messages contain no actual content. They are only small technical signals such as “New message available.” Your app then retrieves the actual encrypted content directly from the respective service (e.g., Matrix or email). This ensures complete data protection—no one but you and your app can see the content of your messages.
⚙️ How to Set Up the Service in Your NTFY App
📲 Setup is incredibly simple:
Open the NTFY app (available free on F-Droid or the Play Store).
That’s it! From now on, supported apps will automatically use this server to receive push notifications.
💡 Many privacy-friendly apps such as Element (Matrix), FluffyChat, or NextPush already support UnifiedPush.
🧰 Technical Background (Simply Explained)
💻 I run my NTFY server on a secured Linux system. A reverse proxy (Nginx Proxy Manager) handles encrypted HTTPS connections. User self-registration is disabled, and strict limits are in place for message and attachment sizes. Uploads without authentication are completely turned off.
This ensures that the server is used solely for push notifications—not for files or chat messages. That prevents abuse and keeps communication lightweight and secure.
🚀 My Conclusion
🔒 I can now offer push notifications without relying on Google or Apple. That gives me full control over technology and data privacy, allowing me to provide clients with a modern and secure alternative.
📡 If you value privacy, data sovereignty, and independence, running your own UnifiedPush service with NTFY is the right choice.

At first glance, October 31st might simply remind people of Halloween. But for those who look deeper, it represents something far greater — a celebration of freedom. Two historic events, centuries apart yet united in spirit, make this day a symbol of intellectual and financial independence.
📜 1517: Martin Luther and the Reformation
On October 31st, 1517, Martin Luther nailed his 95 Theses to the door of the Castle Church in Wittenberg — an act that marked the beginning of the Protestant Reformation. Luther stood up against the corruption of the Catholic Church, especially the sale of indulgences, calling instead for truth, faith, and personal conviction.
🔥 That moment sparked a movement that changed the course of history. It gave individuals the courage to think for themselves and challenged the notion of blind obedience to authority. It was the birth of spiritual freedom — the idea that every person could have a direct relationship with truth and with God, without intermediaries.
💻 2008: Satoshi Nakamoto and the Bitcoin Whitepaper
Nearly five centuries later, on October 31st, 2008, another revolutionary idea emerged — this time not from a monk, but from a mysterious figure known as Satoshi Nakamoto. Amid the global financial crisis, Nakamoto released the Bitcoin Whitepaper, proposing a new kind of money: decentralized, transparent, and free from banks or governments.
⚡ Just as Luther challenged the spiritual monopoly of the Church, Nakamoto questioned the financial monopoly of centralized institutions. Bitcoin became a symbol of digital sovereignty — a tool for those who believe that control over money should belong to the people, not the powerful few.
🌍 A Day of Freedom in Spirit and Finance
October 31st thus unites two revolutions: one of faith, and one of finance. Both were born from dissatisfaction with rigid systems and driven by a yearning for autonomy, truth, and fairness.
💡 Whether a hammer striking a church door or an email containing a nine-page whitepaper, each act carried the same essence — the courage to challenge the status quo and imagine a freer world.
🔔 Conclusion
October 31st is more than Reformation Day or Halloween. It is a Day of Freedom — the freedom to think, to believe, and to build. It reminds us that every great transformation begins with a bold idea and the courage to share it.
🕯️ From Luther to Nakamoto: Five eras, one message — Freedom begins in the mind.

💡 Fast, secure, and simple: That’s the best way to describe the Phoenix Wallet. This app makes paying with Bitcoin as easy as paying with a regular mobile app — whether it’s for a coffee, lunch, or an online purchase.
In this article, you’ll learn what makes Phoenix special, why it’s perfect for instant Bitcoin payments, and why it’s better suited for everyday use than the well-known Electrum app.
🔥 What Is the Phoenix Wallet?
The Phoenix Wallet is a Bitcoin app for Android, developed by the French company ACINQ, one of the leading contributors to the Lightning Network.
The Lightning Network is an additional layer built on top of Bitcoin that allows instant, low-fee transactions. Instead of waiting minutes for a confirmation, payments are completed in just a few seconds.
What makes Phoenix stand out: You don’t need to deal with technical setup, complicated terms, or your own Bitcoin node. The app handles everything for you — and you still stay in full control of your money.
⚡ Why Phoenix Is Perfect for Fast Payments
Many Bitcoin wallets are complicated or made for experienced users. Phoenix, however, is designed so that anyone can use it right away.
Here’s why Phoenix is so convenient:
✅ Automatic Channel Management Phoenix automatically handles all the technical details in the background, like opening or managing payment channels. You don’t have to worry about any of that.
✅ Instant Lightning Payments Payments are usually confirmed instantly, making it perfect for small, everyday purchases — in stores, restaurants, or online.
✅ Simple and Clean Interface The design is intuitive. You can easily see your Bitcoin balance and recent transactions at a glance.
✅ Transparent Fees Phoenix clearly shows when a small fee applies (for example, when opening a new payment channel). There are no hidden costs.
🔒 Security: How Phoenix Protects Your Bitcoin
Security is a big concern for new Bitcoin users — and rightly so! The good news is that Phoenix is built to keep your funds safe and under your full control.
Here’s how:
🔐 You Control Your Money Phoenix is a non-custodial wallet, which means your Bitcoin is stored only on your device, not on a company server. Only you have access to it.
📱 Strong Encryption All sensitive data is encrypted directly on your phone. Even if someone finds your device, they can’t access your Bitcoin without your secret recovery phrase.
☁️ Easy Recovery When you set up the wallet, you get a 12-word recovery phrase. With it, you can restore your wallet anytime — for example, if you lose or replace your phone.
🧩 Trusted Developer Phoenix is developed by ACINQ, one of the key companies behind the Lightning Network. The app is open to community review and regularly updated for security and reliability (OpenSource).
⚙️ Phoenix Wallet vs. Electrum – Which Is Better for Everyday Use?
The Electrum Wallet is one of the oldest and most respected Bitcoin wallets. It’s very powerful — but also quite technical. For beginners, it can feel overwhelming.
Phoenix, on the other hand, is made for simplicity and daily Bitcoin payments.

🧠 Microsoft promotes Windows Recall as a smart, futuristic feature: your PC “remembers” everything you’ve ever seen on your screen – every email, every website, every document. An integrated AI helps you instantly rediscover what you were looking for. It sounds like progress. In reality, it’s a troubling step toward self-surveillance.
👁️ Recall continuously takes screenshots of your desktop and stores them locally. Microsoft claims the data is encrypted and accessible only to you. But wherever data exists, risk exists. Any attacker, malware, or simple oversight could turn this “digital memory” into a serious security breach. What’s marketed as a convenience feature is, in truth, a complete log of your digital life.
⚠️ Many users enable Recall without a second thought – because it sounds practical, because Microsoft seems trustworthy, or because convenience wins over privacy. Nobody would willingly grant an app full access to their photos, contacts, or calendar – yet when Windows offers the same level of data exposure, people often accept it without hesitation.
🔍 Windows Recall demonstrates how easily surveillance can be disguised as a helpful feature.
🐧 Under Linux, such a concept would be almost unthinkable. Open source code, transparent development, and a critical community ensure that control remains in the hands of the user. A system like Linux Mint proves that security, stability, and usability don’t have to come at the cost of privacy.
💡 It’s time to shift the narrative: Windows may win on convenience, but Linux leads where privacy truly matters.
🔗 What is the Mempool? The Mempool (short for Memory Pool) is the waiting area for unconfirmed Bitcoin transactions. Before a transaction is included in a block and officially confirmed, it sits in the Mempool. Here, all pending transactions wait until miners pick them up and add them to a new block. In other words, the Mempool shows what’s happening in the Bitcoin network in real time before it’s written into the blockchain.
💻 I’m now offering a free Mempool service where you can watch Bitcoin transactions live or explore past transactions. It’s perfect for developers, Bitcoin enthusiasts, or anyone curious about what’s going on in the network — fast, lightweight, and privacy-friendly.
🔍 What the service offers
🚀 Live Mempool: Watch new, unconfirmed transactions in real time.
🕓 Historical data: Look up past Mempool events and transaction details.
🧩 Independent server: No big third-party clusters — just a small, private Mempool server for direct access.
🛡️ Why privacy matters This server does not log which IP addresses view which transactions. So if you check your own Bitcoin transactions here, it happens without IP logging — giving you more anonymity compared to many public explorers.
🔒 What is it, exactly? A Fulcrum server is what’s known as an Electrum server for the Bitcoin network. It allows wallet apps such as Phoenix, Electrum, or Sparrow to connect securely and quickly to the blockchain – the decentralized database that records all Bitcoin transactions. Instead of downloading the entire Bitcoin blockchain, wallets can use a Fulcrum server to fetch only the data they need — efficiently, privately, and without relying on big centralized providers.
⚙️ Technical Details My Fulcrum server runs at the following address: 👉 fulcrum.it-service-commander.de:50002 The connection is fully SSL-encrypted, ensuring all communication is secure. Behind the scenes, it’s powered by Bitcoin Core 29.2, directly connected to the Bitcoin network.
💼 Why I’m Offering This As an IT service provider, I work with a few clients who are increasingly interested in Bitcoin, self-custody, and digital security. Most wallet apps automatically connect to public servers on the internet — and you never really know who operates them or what kind of data they collect.
With my own Fulcrum server, I provide my clients (and anyone interested) with a trusted, privacy-friendly, and stable infrastructure they can easily configure in their wallet app.
📱 How to Connect
Getting started is simple:
Open your wallet app (e.g., Phoenix, Electrum, or Sparrow).
Save the settings — and you’re all set! Your wallet is now securely connected to my Fulcrum server.
🔧 Benefits for My Clients ✅ Fast synchronization with the Bitcoin blockchain ✅ Fully encrypted communication via SSL ✅ No dependency on unknown third-party servers ✅ Ideal for businesses integrating Bitcoin into their IT infrastructure ✅ Transparent, European-based infrastructure — operated by a local IT provider
🚀 Conclusion With my public Bitcoin Fulcrum server, I aim to make secure, decentralized technologies more accessible — especially for small and mid-sized businesses. Anyone using Bitcoin should understand that real trust comes from transparency and open systems — and that’s exactly what this service represents.
