An MCP server is not a new API. It is a thin layer over the one you already have
Somewhere in the last year, "do we need an MCP server?" joined the list of questions that arrive in a brief before anyone has said what the thing is for. It is usually framed as MCP vs API, as though the Model Context Protocol were a newer kind of AP...

A week of green runs, and the pipeline was waiting for me
On 1 September at 10:57 UTC the monthly ingest ran. It opened issue number 3 of the magazine, picked the vertical from the source registry, wrote 19 candidate sources into Postgres with stage = 'discovery', and opened a GitHub issue telling me it was...

How to get alerted when someone changes your DNS records
> TL;DR. Most DNS changes do not take your site down. A new MX record or an edited SPF record usually still resolves, so your uptime checks stay green. To catch these changes, list every record a name should have. Then get an alert when the live answ...

Multi-tenant PageSpeed monitoring under $100: what agencies actually buy
The purchase is rarely another free checker. It is scheduled portfolio coverage, shared history, and flat organisation caps that survive twenty client sites. An agency can open ChatGPT, paste a PageSpeed Insights URL, and get a plausible fix list be...

What PageSpeed monitoring stack should an agency run in 2026?
Most agencies do not need three products on day one. Pick a default PageSpeed monitoring stack, then add RUM only where money URLs justify it. The roster hits twenty client sites, yet the “monitoring stack” is still a shared folder of PageSpeed Insi...

Google says on-call needs eight engineers. You have three.
> TL;DR. Google's SRE book works out that a 24/7 on-call rotation needs at least eight engineers. A team of two or three cannot reach that number, so it has to change what the number is built from: which alerts page a person, which hours are covered,...

Oh Dear alternative? Uptime green is not Core Web Vitals portfolio monitoring
Searching for an Oh Dear alternative usually lands you on more uptime tools. Green reachability is not a Core Web Vitals portfolio. The uptime dashboard is green, SSL is fine, and the status page is quiet, yet a client still forwards a PageSpeed Ins...

ICMP vs TCP vs UDP: the difference, explained for developers
> TL;DR. ICMP, TCP and UDP all travel inside IP packets, but they ask different questions. ICMP echo ping asks "does this address answer at all?" and needs no port. TCP asks "is a program listening on this port?" and gets a clear yes, a clear no, or ...

AWS's Own Dashboard Could Not Say It Was Down. Four of Our Monitors Had the Same Bug.
A signal has three states and most code stores two. When “cannot measure” is written with the same value as “fine,” the alarm branch becomes unreachable in exactly the situation the alarm exists for. On 7 December 2021, the operations teams inside...

Treo vs Apogee Watcher: CrUX Scale, Competitor Benchmarks, and Agency Portfolios
After the CrUX Dashboard and Looker Studio report retired, many teams rebuilt their field-data workflow from PageSpeed Insights, Search Console, and third-party CrUX explorers. Treo is one of the products agencies shortlist when they want CrUX at por...

Why is my Chrome UX Report much worse than Lighthouse? How can I improve it?
CrUX field percentiles often look worse than a green Lighthouse run on the same URL. Here is why the gap is normal, what moves real-user Core Web Vitals, and what not to chase. On Monday the Lighthouse performance score on checkout was 94. Mobile la...

We built MailOps for our own Modoboa servers. Now it is a product
Self-hosted Modoboa mail worked for administration. Server health, mailbox estate, and SPF–DKIM–DMARC bounce diagnosis still lived in SSH and spreadsheets until we productised the ops layer we actually used. The bounce arrived on a Friday. The Modob...

Your domain can expire while your uptime monitor stays green
> TL;DR. One HTTP check on your homepage is not enough to know your site works. It cannot tell you when your domain expires, because an expired domain still returns 200 OK from a parking page. Mail dies at the same time, just as quietly, and you keep...
