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.
“Vietnam Knowledge is an independent reference site about Vietnam — its history, culture, regions, language, food, economy, visa policy and the common scams worth knowing before you arrive.”
“The country is rewarding and complicated, and most of the English-language writing about it falls into one of two camps: marketing copy from tour operators, or a thin travel-blog summary. This site is neither. It tries to be plain, calm, accurate, and updated when policy changes — especially the visa policy, which has shifted meaningfully in the past two years.”
“Regions — North, Central, South; plus the 34 provinces and municipalities (Vietnam merged 63 units into 34 on 1 July 2025).”
“Independent editorially; funded partly by travel affiliate commission, disclosed at /editorial-policy#funding.”
“Where a claim is time-sensitive (visa rules, prices, regulations), we try to date it. If you notice something out of date or wrong, please get in touch — corrections are appreciated.”
“Dated changes to visas, traffic law, taxes, hospitals — material changes you should know.”
“Static tools that work offline, store no data, and give straight answers.”
“Printable, checkbox-marked lists for the high-stakes Vietnam tasks.”
