SGLang Crossed 400,000 Production GPUs: Picking Your Self-Hosted PaaS's Default Model Server
SGLang now serves 400,000+ production GPUs, making it a real second default next to vLLM. Benchmarks, workload maps, and a decision matrix for choosing the model server on your own GPU pool.
SSH3 in 2026: QUIC Shell Access Grew Up, but Its Own Forks Say Don't Ship It Yet
SSH3 re-implements SSH on QUIC, TLS 1.3, and HTTP/3 with 3-round-trip setup, roaming sessions, and UDP forwarding — but unaudited code and a renamed spec mean 2026's honest posture is a bastion-side trial, not a cutover. Here is the adoption map.
Ingress-NGINX Is Retired. Your PaaS Inherited Its Quirks — Audit Them Before They Become Outages
Ingress-NGINX retired in March 2026, leaving five silent routing behaviors behind. This behavior-by-behavior audit maps each quirk to what breaks on a naive Gateway API migration — and what a self-hosted PaaS routing layer must now own explicitly.
Microsoft's Document Database Rides CloudNativePG: What That Verdict Means for Your Fleet's Postgres Layer
Microsoft's DocumentDB Kubernetes operator creates CNPG Cluster resources instead of reimplementing HA and backups, injecting its gateway through a CNPG-I plugin. What that architecture proves about standardizing a self-hosted fleet's Postgres layer — and the honest cases for not doing it.
Heroku's Shutdown Isn't Announced — Your Contingency Checklist Should Be Done Anyway
InfoWorld reads Heroku's February 2026 sustaining mode as a prelude to phase-out. No shutdown is announced — but the export-ready audit (generation and stack inventory, data backup drills, container images off the Cedar-only registry, config extraction, add-on disentanglement order) is the same work as scoping your migration.
Your Read-Only Tool Is the Sandbox Escape: What Claude Code's /proc/self/environ API-Key Leak Teaches About Agent Deploy Pipelines
Microsoft researchers hid instructions in a GitHub issue comment, steered Claude Code's Action to its unsandboxed Read tool, and walked out with a live API key. Here is the full four-step chain plus a 7-point audit for your own agent deploy pipeline.
GitHub Purges Node 20 From Actions Runners on September 23: What Breaks, What to Bump, and Why Your Own Metal Sets Its Own Deadline
On September 23 GitHub removes Node 20 from every hosted Actions runner, and workflows pinned to node20-era actions fail outright instead of warning. The exact majors to bump, the runner floor for self-hosted fleets, and why owning your build plane turns the next vendor deadline into a planned window.
Heroku-20 Is Dead and Heroku Is Frozen: Rebuild Your Stack With pack build Before You Migrate
Heroku-20 can't deploy and Heroku's roadmap is over — reproduce your frozen build locally with pack build and Heroku's own CNB builder, fix the five classic-buildpack-isms that break outside Heroku's base image, and carry a portable OCI image to your next platform.
kube-hetzner Just Made Leap Micro the Default Node OS: What the Switch Off MicroOS Means for Your Hetzner Cluster
kube-hetzner's v3 line boots Leap Micro on every new nodepool while existing MicroOS nodes stay put. What the switch means, why fixed-point releases beat rolling ones for production nodes, and how Leap Micro compares to Talos.
