How it is built, by role
The same roles apply across the whole collection. Nothing in this block is specific to this site; what the site says about itself is quoted word for word below it.
- 1
Edge network
Visitors reach a site through an edge layer: a content delivery network with a web application firewall in front of it.
- 2
Application host
The edge talks to an application host that serves the site and renders its pages.
- 3
Data
What the pages show comes from a relational database or, for a site pre-rendered at build time, from data files built into its release.
- 4
Scheduled measurement
The collection measures its sites on a schedule: content dates and site health nightly, page counts read from each site’s sitemap weekly. Every reading is kept with its date. A site too large to re-walk is not re-measured, and shows no trend.
- 5
Public status feed
A monitoring panel sends a signed report on uptime, deploys and backups once a day, and the Operations page publishes it. A figure on this page that comes from that report says so.
In the site's own words
Each passage is copied unaltered from a page the site publishes, with the address it was taken from and the date we took it. We add nothing between them.
“Migration Watchdog is an independent, data-driven monitor of illegal and irregular immigration to the United Kingdom and of the state's handling of it.”
“Data is taken from the Home Office 'Small boat activity in the English Channel' publication (updated weekly) and the quarterly Immigration System Statistics.”
“There is no machine-readable government costs dataset, so every figure on this page is a curated citation from a National Audit Office report or the Home Office Annual Report and Accounts, quoted exactly and linked.”
“The download page: every cleaned series the site renders, as CSV and JSON, grouped into six catalogues — arrivals and migration flows, the asylum system, enforcement and detention, places and local impact, money, and Parliament and regulation.”
“Every figure carries its source, period and retrieval date, and the build genuinely fails if one does not.”
“Where no official denominator exists — as for offending by nationality — no rate is published and the absence is stated instead.”
“Where a whole sentence is quoted from a longer document, it is checked character-for-character against the source before it ships, and the link goes to that source in context.”
“Self-funded by its operator. No advertising, no donations, no political funding, no paid content. If that ever changes, it will be disclosed on this page first.”
