Hetzner's April Price Hike, Three Months Later: Why a 37% Raise Still Leaves Your 3-Node Fleet Cheaper Than Render and Railway

Hetzner raised cloud prices up to 37% on April 1, 2026, but a 3-node CX22 fleet still costs ~$14/month with 60 TB included — versus $21–$85 on Render and $25–$240 on Railway. Line-by-line bills and an egress sensitivity table show where the margin narrowed and where it still clears.

Hetzner's $40 → $103 Hike Broke US Math: Hetzner US vs OVHcloud vs Domestic VPS, Line by Line

Hetzner's CCX23 jumped from $39.99 to $102.99 on June 15 (+157.5%). For a US team the headline is only half the bill — US regions include 1 TB, not 20 TB. A 5 TB workload costs $107 on Hetzner US, $37 on OVHcloud unlimited, and $116 on a domestic VPS.

Fly.io's Two New 2026 Bills: What Private Networking and Snapshot Metering Actually Add Next to a Flat Hetzner Box

Fly.io started billing volume snapshots in January 2026 and MPG inter-region private networking in February 2026. A worked, line-by-line recompute shows the hobby app stays at $0 delta while a multi-region production stack adds $0.90–$9.20 a month, versus the same containers for €3.79 flat on Hetzner.

The EU Just Legislated Who Can Sell Cloud to Its Governments: What CADA's Four Tiers Mean for Your PaaS Choice

On June 3, 2026 the EU turned its SEAL-0 to SEAL-4 sovereignty grades into procurement law. A concrete map of CADA's four assurance levels, where US hyperscalers hit a structural wall, and why a fleet on owned Hetzner/OVHcloud/Scaleway hardware clears a bar a US-headquartered PaaS cannot.

Eleven Minutes, Zero Humans: What Kairos's Self-Healing Upgrades Teach a Bare-Metal PaaS

A CNCF Kubestronaut ran an 11-minute, zero-human Kubernetes upgrade on Kairos's A/B immutable OS — and documented every bug that almost broke it. Here is the pipeline, the two fixes that saved etcd quorum, and how to translate it to a Hetzner + Cluster API fleet.

Zero Egress, Metered State: What Cloudflare's January 2026 Durable Objects Bill Actually Costs Against a Flat Hetzner Box

Cloudflare's zero-egress promise still holds for R2 and CDN — but SQLite-backed Durable Objects started billing $1/M writes and $0.20/GB-month on January 7, 2026, with Workflows steps following August 10. A worked table prices small, medium and heavy stateful workloads against a €3.79 Hetzner CX22 with flat 20TB and local Postgres.

Chaos-Test Your Cluster API Fleet: Three LitmusChaos Experiments That Prove Self-Healing Before 3 A.M. Does

MachineHealthCheck promises your fleet self-heals — but few teams have watched it happen. A runnable LitmusChaos suite for CAPH/CAPD fleets: kill a kubelet, partition a control plane, fill a disk — and assert remediation fires within nodeStartupTimeout, workloads reschedule, and the fleet converges without a human.
