This is an official ODERSA website. Here’s how you know

The official domain

The address of this site ends in odersa.org. Every service the association runs sits on a subdomain of odersa.org and nowhere else. If the address in your browser’s address bar does not end in odersa.org, this site is not ours.

Free, and no account

Everything is open straight away. No sign-up, no account, no password, no subscription, no advertising. Nothing is held back for those who pay, because there is nothing to pay for.

No data collected

This site does not follow you: no tracker, no tracking cookie, no measurement tool built into these pages, and nothing measured on your device. Our host counts requests in aggregate, as any server that answers does: a total, never a profile. You do not have to take our word for it: open your browser’s developer tools, go to the Network tab, and reload the page. You will see the full list of what the site asks for. Everything comes from odersa.org, nothing goes anywhere else.

Free to reuse

The content is published under the CC BY 4.0 licence. You may copy it, translate it, print it and pass it on, for your classes as much as for the people around you, on one condition only: credit ODERSA.

What “online” means here

A reading that hides its limits is not a reading. Here is exactly what the measurement proves, and where it stops.

What the check proves

  • The check starts in your browser: it measures the real path between your connection and our servers, not the view of a monitoring machine sitting somewhere else.
  • The probe reads the real HTTP response code, because each of our sites names this page as allowed to read it: a direct 200 shows as “Answering”, an answer reached through a redirect as “Answering, differently”, and a refusal from the server or an answer your browser sets aside as “Blocked or failing”.
  • The time shown is the time of the check. It changes every time you run the measurement again, and it has nothing to do with when this page was published.
  • Every address contacted is one of ours, and they are all listed here. Open your browser’s network inspector: there are no others.

What it does not prove

  • A site that answers is not a site that is right: the measurement says a server replied, not that the page you came for is up to date.
  • A check that runs past a few seconds shows as not checked, never as down: nothing tells a stopped server apart from a slow connection.
  • “Blocked or failing” does not choose between the two: when a browser sets a response aside for a security rule, it tells this page no more than a server that is down would. And a site that answers here can still be out of reach for you elsewhere, behind an institution’s filter or a network operator.
  • Nothing is recorded. This page keeps no history and sends no measurement anywhere: no one but you sees this result, and there is no server to receive it.

A general outage is read elsewhere

Our sites are served by Cloudflare. When it is their network that fails, all of our sites go down at the same instant and this page can no longer measure anything: the host’s own dashboard is then the only thing that counts.

See the state of the Cloudflare network

A link, not a call. This page contacts no outside service, neither on load nor on click: it gives you the address and leaves the choice to you.

Without JavaScript, and offline

The measurement needs JavaScript, because it happens in your browser and nowhere else. Without it this page stays whole: it says what it measures, it gives the address of every one of our sites, and it points to the host’s dashboard. It simply shows no state, because none has been measured.

Offline it is the same: nothing can be reached, so nothing is shown. An invented state would be worse than a missing one. And when nothing answers, nothing tells a cut network apart from our servers: the page does not settle it, it says so.
