Hetzner's 45-Hour ASH Load Balancer Outage: What a Managed LB Costs a Fleet That Doesn't Run Its Own
A Hetzner-managed Load Balancer in ASH went down for 45 hours on July 13, 2026, taking every healthy tenant behind it offline. Here's the actual blast-radius math, and what running kube-vip or MetalLB yourself instead would have cost and bought back.
Kubernetes 1.36 Ships the Metric That Finally Proves Your Route Controller Isn't Wasting API Calls
Kubernetes 1.36 adds a counter that proves whether your route controller is syncing on real node changes or wasting API calls on a timer. Here's what it measures, how to check if your Hetzner CCM exposes it, and a PromQL alert that catches a stuck node join before it becomes an outage.
Kubernetes 1.36's HPA Can Now Scale to Zero: What It Actually Changes for Idle-App Billing
Kubernetes 1.36 finally defaults HPAScaleToZero on, but it only solves half the scale-to-zero problem. Here's the exact split, real cold-start numbers from Render and Fly.io, and a worked cost model for a self-hosted PaaS's dormant-app billing.
What Self-Hosting OpenMeter's Kafka+ClickHouse Stack Actually Costs a Git-Push PaaS
OpenMeter's self-hosted stack adds two new stateful services — Kafka and ClickHouse — to bill per millisecond. Here's what that actually costs in Hetzner hardware and ops burden against billing tenants on signals a PaaS already tracks for free.
Railway's Three Years Without a Price Increase vs Render's April 2026 Repricing: What Sticker Stability Actually Signals
Railway hasn't touched its plan fee or rate card since 2023; Render restructured its entire workspace pricing in April 2026. Here's what the two timelines actually reveal about cost structure, growth strategy, and why a flat sticker price isn't the same claim as a flat bill.
Zeabur's $5 'No Sleep' Credit vs a €4.35 Hetzner Box: What You're Actually Paying For
Zeabur's $5/month Dev plan sells freedom from cold-start sleep. A line-by-line recompute of what that $5 credit actually covers on Zeabur's metered RAM pricing versus a €4.35 Hetzner CX22 that was never billed by the minute at all.
Blacksmith and Depot Colocate Docker Layer Cache on NVMe: What 40x Faster CI Builds Mean for Self-Hosted Build Pipelines
Blacksmith and Depot claim 20x-40x faster Docker builds by moving the layer cache onto NVMe disk colocated with the build machine. Here's the actual mechanism, and what it means for a self-hosted PaaS that already owns its build hardware.
Dokploy vs. Coolify in 2026: What Happens the Day You Click 'Add Server'
Coolify and Dokploy both added multi-server features in 2026. Neither provisions a machine, heals a dead node, or wires up a load balancer without a human at the keyboard. Here's the feature-by-feature gap against a Cluster API fleet.
eBPF Made Continuous Profiling Nearly Free — But Someone Still Has to Store It: Parca vs. Pyroscope on a Self-Hosted Fleet
Parca and Pyroscope both run eBPF-based continuous profiling under 1% CPU overhead. Here's what standing either one up as a Cluster API service actually costs in storage and operational surface, worked against Datadog and Grafana Cloud's own profiling bills for the same fleet.
