Open source vs "trust us": how to verify a cloud storage privacy claim before you switch

A privacy claim you can't check is just marketing. Here's how to verify a cloud storage provider's encryption and "open source" claims yourself — with the Proton Lumo overclaim and the Mullvad raid as the cautionary and the proof.

How a Zero-Knowledge Backend Is Architected: Storing Data You Cannot Read

A zero-knowledge server only ever sees ciphertext, which quietly breaks search, dedup, and previews, and changes exactly what a breach can leak. Here's the full backend picture, and how to check a provider's claim is architectural, not marketing.

Why European Companies Are Leaving US Cloud Providers in 2026 — and What to Check Before You Do

European sovereign cloud spending jumps from $6.9B to $12.6B in 2026, and the Tech Sovereignty Package gave it a regulatory push. But a European flag on a pricing page is not jurisdiction. Here is what to actually check.

The True Cost of Cloud Storage: The Five Line Items the Per-GB Price Hides

Object storage advertises a low per-GB rate, then bills you for egress, requests, cold-tier retrieval, and replication on top. Here are the five meters behind a cloud bill — and why a flat per-TB price removes four of them.

Self-Hosting Nextcloud vs a Managed Zero-Knowledge Provider: The Honest Cost-and-Effort Breakdown

A Recovery Phrase for Your Files, Not Your Coins: How BIP39 Backs Up Encrypted Storage

Anycast, DNS Failover, and Round-Robin: How Traffic Actually Finds a Healthy Server

Routing a user to a live backend isn't one decision — it's three stacked layers: anycast at the network, DNS failover at resolution, proxy health checks at the connection. Each fails differently, and the failures compound.

The honest guide to leaving Google Drive, Dropbox, iCloud or OneDrive for an EU cloud

Pick a provider whose company — not just its servers — sits under EU jurisdiction, ideally zero-knowledge and open-source. Export your files, verify the copy, then bulk-move via CLI or WebDAV. You trade some integration convenience for real jurisdiction and no lock-in.
