Real systems, with the reasoning left in: what the problem was, what I chose and why. https://www.pagetech.solutions/workshop/ 2026-10-16T00:00:00Z Jamie Pagehttps://www.pagetech.solutions/about/ https://www.pagetech.solutions/assets/favicon-32.png © PageTech Solutions Limited https://www.pagetech.solutions/workshop/one-package-four-fixes/ 2026-10-16T00:00:00Z 2026-10-16T00:00:00Z

A .NET security advisory broke my builds overnight with no code change. Why the right fix differed in each of four repositories, and why audit stayed on.

https://www.pagetech.solutions/workshop/seventy-nine-routing-rules/ 2026-10-16T00:00:00Z 2026-10-16T00:00:00Z

My hosting config was 98 bytes from its cap. 79 of its rules restated the platform, and the redirects among them were dropping ad click IDs.

https://www.pagetech.solutions/workshop/dashboard-honest-labels/ 2026-10-09T00:00:00Z 2026-10-16T00:00:00Z

Five ways my own dashboard misled me, and a contact form that took 146 enquiries and accepted 3. Why every figure needs a label saying what it counts.

https://www.pagetech.solutions/workshop/green-health-check/ 2026-10-09T00:00:00Z 2026-10-16T00:00:00Z

Three releases where the pipeline was wrong about production, and why deployment success, service health and build identity are separate claims.

https://www.pagetech.solutions/workshop/invoice-matching/ 2026-10-09T00:00:00Z 2026-10-16T00:00:00Z

An invoice matcher that matched 5 of 62. A regex that read a heading as a reference, a repair that swapped one false value for another, and silent failures.

https://www.pagetech.solutions/workshop/quiet-morning-email/ 2026-10-09T00:00:00Z 2026-10-16T00:00:00Z

For a scheduled email, silence is the failure, and nothing alerts on silence. Five quiet failures of a twice-daily digest, and what notices them now.

https://www.pagetech.solutions/workshop/shipping-the-app/ 2026-10-09T00:00:00Z 2026-10-16T00:00:00Z

Roughly half the commits behind a small internal app went on packaging, signing, distribution and sign-in. Five failures that came after a green build.

https://www.pagetech.solutions/workshop/six-weeks-of-done/ 2026-10-09T00:00:00Z 2026-10-16T00:00:00Z

A daily contact sync logged ‘done’ for six weeks while a missing permission refused every read. Why a refusal must fail the run, not pass as an empty mailbox.

https://www.pagetech.solutions/workshop/unsubscribe-ledger/ 2026-09-11T00:00:00Z 2026-10-16T00:00:00Z

Every sending platform keeps its own list, and the obligation stays with you when you move. A suppression ledger you own, and the permissions behind it.

https://www.pagetech.solutions/workshop/deleting-the-last-connection-string/ 2026-09-07T00:00:00Z 2026-10-16T00:00:00Z

Removing long-lived keys from four services in favour of managed identity. The code change is trivial; everything around it is where the time goes.

https://www.pagetech.solutions/workshop/firewall-sync-service/ 2026-09-06T00:00:00Z 2026-10-16T00:00:00Z

A dynamic IP against a locked-down key vault and database. Why a script was the wrong shape, and the debounce race that made the service report itself healthy.

https://www.pagetech.solutions/workshop/oauth-integration/ 2026-09-04T00:00:00Z 2026-10-16T00:00:00Z

Adding a second sign-in provider is where verification systems go wrong silently. Why the fix was structural, and why the host refuses to start.

https://www.pagetech.solutions/workshop/bulk-editing-a-live-mailbox/ 2026-09-02T00:00:00Z 2026-10-16T00:00:00Z

Preview mode before apply mode, a safety cap, and going live only on an explicit go-ahead. Plus what the low-code platform charged for the privilege.

https://www.pagetech.solutions/workshop/self-hosted-build-agent/ 2026-09-02T00:00:00Z 2026-10-16T00:00:00Z

Eight of twenty-six jobs failed and the VM was deleted after 32 hours. What the failures actually said, and what changed when it was rebuilt four months later.

https://www.pagetech.solutions/workshop/api-routes-that-never-existed/ 2026-08-31T00:00:00Z 2026-10-16T00:00:00Z

A proxy with 170 routes, fifteen of which pointed at endpoints that do not exist. Why nothing caught them, and the two related failures alongside.

https://www.pagetech.solutions/workshop/azure-cost-reductions/ 2026-08-30T00:00:00Z 2026-10-16T00:00:00Z

Bursty compliance work on an always-on host. Why scale-to-zero was the last step and not the first, and what the move actually cost and saved.

https://www.pagetech.solutions/workshop/acr-purge-fail-closed/ 2026-08-28T00:00:00Z 2026-10-16T00:00:00Z

A scheduled registry purge deleted the image production was running on. Why the obvious fix was not enough, and why deletion jobs have to fail closed.

https://www.pagetech.solutions/workshop/testimonial-verification/ 2026-08-25T00:00:00Z 2026-10-16T00:00:00Z

Verifying a referee's identity without letting that imply approval. Two records kept separate, two levels, and only one of them public.

https://www.pagetech.solutions/workshop/webmcp/ 2026-08-18T00:00:00Z 2026-10-16T00:00:00Z

The tools an AI agent can call on this site instead of scraping it: availability, rates, services, the FAQ and a staged contact enquiry. 100% remote.

https://www.pagetech.solutions/workshop/how-this-site-works/ 2026-08-09T00:00:00Z 2026-10-16T00:00:00Z

Two walk-throughs of this site's own machinery: what happens when you press send on the contact form, failure paths included, and what an AI agent sees.

https://www.pagetech.solutions/workshop/email-authentication-reports/ 2026-06-23T00:00:00Z 2026-10-16T00:00:00Z

DMARC and TLS-RPT reports arrive daily and almost nobody reads them. Ingesting them from the mailbox they already land in, and why the DNS half mattered more.
