Docker Hub Almost Cut You to 40 Pulls an Hour: The Math for Sizing Your Own Registry Cache

Docker Hub Almost Cut You to 40 Pulls an Hour: The Math for Sizing Your Own Registry Cache

Docker's walked-back 10/40-per-hour limits were a preview, not a false alarm: a 15-developer team with ephemeral CI runners and a 12-node cluster hits today's enforced 100/200-per-6-hour buckets on an ordinary Tuesday. The full pull ledger, the tipping-point formula, and how to size and wire a registry cache — registry:2 or Harbor — into a Cluster API fleet.

Your Cluster Runs at 8% CPU: Bin-Packing Defaults for a Self-Hosted Fleet That Can't Return Capacity

Your Cluster Runs at 8% CPU: Bin-Packing Defaults for a Self-Hosted Fleet That Can't Return Capacity

Cast AI's 2026 report puts average Kubernetes CPU utilization at 8% and memory at 20%. On elastic cloud that's an expensive bill; on owned hardware it's capacity you already paid for and can't return. Concrete request/limit defaults, a bin-packing scheduler config, and a worked Hetzner-vs-cloud cost delta.

Railway's July 2026 US East Outage: What One ISP's Bad Route Cost Every App — and What Owning the Network Costs Instead

Railway's July 2026 US East Outage: What One ISP's Bad Route Cost Every App — and What Owning the Network Costs Instead

One carrier's backbone degradation left every app in Railway's US East zone degraded for over four hours — including 20 minutes with no internet route at all. A worked breakdown of what the outage cost and what owning your own network path actually costs, from a €40 Hetzner box to a full ASN with dual transit.

IPv6-Only Worker Nodes on Hetzner: What Dropping the €0.50 IPv4 Line Item Saves a 10–50 Node Fleet, and What Breaks First

IPv6-Only Worker Nodes on Hetzner: What Dropping the €0.50 IPv4 Line Item Saves a 10–50 Node Fleet, and What Breaks First

Hetzner bills every primary IPv4 at €0.50/month while IPv6 is free. The real savings math for a 10-50 node CAPH fleet after the June 2026 repricing, why GitHub and ghcr.io break first on IPv6-only nodes, and the four bridges — public NAT64, Jool, a NAT gateway, or a registry cache.

Vercel's Four Repricings Since 2024: What the Pattern Predicts for Your Next Bill Shock — and What a Fixed-Price Box Actually Fixes

Vercel's Four Repricings Since 2024: What the Pattern Predicts for Your Next Bill Shock — and What a Fixed-Price Box Actually Fixes

Vercel re-modeled its billing four times in eighteen months — granular meters, Fluid Compute, Active CPU, then credits. Here is the full timeline, what the 3-10 month cadence means for your budget, and a worked comparison against a flat-rate Hetzner box where egress variance is zero.

Your AI Agent's Debug Loop Costs Grow Quadratically, Not Linearly — Here's the Math

Your AI Agent's Debug Loop Costs Grow Quadratically, Not Linearly — Here's the Math

A 50-step AI agent debug loop bills 26x more than the tool calls it actually made — because every LLM call resends the entire conversation history. Here's the math, the real dollar cost for a deploy-from-chat MCP server, and the fix that actually bounds it.

Cloudflare D1's Per-Row Meter Turned 765,000 Rows Into a $134 Bill: What a 10GB-Per-Database Cap Costs a Bundled PaaS Database

Cloudflare D1's Per-Row Meter Turned 765,000 Rows Into a $134 Bill: What a 10GB-Per-Database Cap Costs a Bundled PaaS Database

A published $134 Cloudflare D1 bill — 95% of it a single line item of 127 billion metered row reads from a missing index — is a concrete look at what per-row database billing and a 10GB-per-database cap actually cost, against a self-hosted SQLite-plus-Litestream setup where a bad query is a latency problem, not an invoice line.

Docker Hub's 2026 Price Hikes Make the Case for a Self-Hosted Harbor Registry

Docker's 2026 price hikes and pull rate limits push a busy CI pipeline into a $1,800/year seat-priced plan for one feature: unlimited pulls. Here's what a self-hosted Harbor registry costs instead.

Docker Hub's Unauthenticated Pull Limits Are Still 100/6hr: When a Self-Hosted Registry Actually Pays Off

Docker Hub's Unauthenticated Pull Limits Are Still 100/6hr: When a Self-Hosted Registry Actually Pays Off

Docker Hub still caps unauthenticated pulls at 100/6hr and free accounts at 200/6hr in 2026. A concrete threshold for when a CI fleet should authenticate, pay for Pro, add a pull-through cache, or run its own registry.
