For the desperate people whose tests all just broke, I have a page on my public endpoint testing server that exactly reproduces the classic design: https://example.testserver.host/. You can just use update the URL and go back to blissful ignorance.
What kind of tests would this break? Aside from the advice on the page itself (which, iirc, is new anyway), i'm wondering why any testing would actually involve the contents of design of the page. Just a weird 'sanity' check?
Our saas had an internal-use, undocumented, publicly accessibly but not publicly used (by us) health endpoint that included an internal version number.
We removed the version and a few customers complained we broke their stuff.
> For the desperate people whose tests all just broke...
The web page at example.com is maintained as a courtesy by IANA in order to explain the purpose of the example.com domain to wayward humans.
In the nomenclature of RFC 2119, one MUST NOT design computer systems that rely on the correct operation of an HTTP server at that domain. [0] Plus, it's _really_ rude to pound on a small-scale service being provided as a courtesy... go hit the home page of a tech megacorp (such as Microsoft or Google) or the status page for a major CDN (such as Cloudflare or Akamai) instead!
[0] I expect that someone here will want to pop up with a "gotcha" where they say something like "Oh, but IANA's email says that automated use is strongly recommended against, rather than prohibited and besides, they can't actually stop me from doing it!". To that, I reply "Sure, and standards-writers can't actually stop implementers that do the profoundly antisocial thing and do the things they MUST NOT. As any adult who's been paying attention to the world around them throughout their lives knows, there's only so much you can do to stop people who are very determined to be enormous assholes.".

If 1.1.1.1 ever stops responding to pings…
anyfoo 2 hours ago [-]
I don’t use this one, because I remember when long, long ago it was in some random IP address block belonging to someone, and this particular address didn’t reply to ping.
Likely for good reason, even back then there would have bound to be lots of misconfigured endpoints trying to access 1.1.1.1, so just blocking it at the earliest point possible kept at lot of the annoyance away. Nowadays, it’s an anycast address, so it’s slightly less bad.
But for me, old habits die hard.

If 1.1.1.1 fails, I will try 8.8.8.8
ButlerianJihad 5 hours ago [-]
> 1.1.1.1
Pinging such an address is inherently a troublesome practice. This address, like many public DNS servers (resolvers as well as root and authoritative ones), uses "anycast" routing methodology.
Pinging an anycast address will yield a cornucopia of different results. Of course, people who naïvely "ping" a recognizable or easy-to-type IPv4 address get what they deserve, especially when they enshrine it into software, unit tests, or the LLM coughs up such tokens on their behalf.
Fundamentally, the question is "what do you really want to test?" by pinging a particular IPv4? Do you want to test Layer 3 connectivity? Test your ISP's backbone and connectivity? Test only your upstream router? Test the existence of ICMP in your stack and theirs?
... the possibilities are endless. Your router can do anything. Ping zombo.com.
zettabomb 3 hours ago [-]
Why is pinging an anycast address an issue? Most people, myself included, ping addresses like 1.1.1.1 to check for internet connectivity. It's a perfectly valid check, you don't need a fine grained test all the time. If it fails, then I go looking in detail. Most of the time it will pass.
Pinging a domain name could fail for a variety of other reasons, particularly if it's not a reliable site. Cloudflare's business is being reliable; few sites would be a better choice.
its-summertime 2 hours ago [-]
The problem is pinging 1.1.1.1 can end up hitting a really really close-by server. You could be having ISP issues and 1.1.1.1 could end up being closer to you than the issue is, so you get okay ping results but still unable to access resources on the other side of the issue
zettabomb 2 hours ago [-]
You're thinking far too hard. If I can ping 1.1.1.1, it means traffic is flowing from inside my network, to outside my network. I'm not going to diagnose my ISP's issues, that's their job, I just need to know that it's not my problem.

Fun fact, ping is the standard windows way to wait a given number of seconds[0]. You're supposed to ping 127.0.0.1, but I saw a lot of scripts pinging 1.1.1.1 or 8.8.8.8
Don't see why this is relevant, ping is not traceroute or http. If you just want to test if packets can leave your network then its a good enough test and anycast doesn't affect that.

Well, no. The purpose of the redesign is to move as much of the page content as possible into an external javascript file. There's no question of what parts of the page require javascript; the question is what parts of the page can be moved into javascript.

example.com is not a user-facing service. I don't want to disparage the designer, but it's not meant to be pretty. It's meant to be small so you can copy its response to an automated test or visually verify its correctness, or just out of the bandwidth consideration you'd still be serving it to billions of requestors, even if you insist it's not meant to be used that way.

creatonez 3 hours ago [-]
> and was wondering why I saw a giant blob of dynamic nonsense instead of a small bit of markup.
It's 4.5x the size of the original. Which sounds bad, until you notice this means it's 2540 bytes and serves the explanatory text in 6x the number of languages. And it's now served with brotli compression, for a total of 1713 bytes. Or 334 bytes if you only request the HTML (which still has a usable page with the full English version of the explanatory text), like a basic scraper or a health check would. So for the vast majority of traffic, it's now half the size of the old version.
I notice it's been through several revisions, the pre-2025 version of the site most people are familiar with is 1270 bytes because it didn't make use of any minification, and it also triggered an unnecessary `/favicon.ico` request because it didn't use the trick to cancel the request.

Same here! Yes, I used it as the well-known site that supported unencrypted http and no HSTS. Yes, I was one of those guys using the site "as a service" rather than simply documentation. Admittedly, it was perhaps interchangeable with other sites, but since it reliably worked for that purpose, I couldn't be arsed to find other ones.
Isn't there a dedicated site called nohttps or something? NeverSSL? I just tried http NeverSSL, and it redirected me to an https page with a random hostname and an Amazon SSL certificate!
Does example.com still function this way, with http and no HSTS? I noticed that my Chrome browser was immediately redirected in the customary way.
Are you perhaps on an untrusted network which is spoofing that url to make it redirect somewhere else?

notpushkin 3 hours ago [-]
It has SSL on the main domain, and some subdomains without SSL (wildcard perhaps?). The main domain (when accessed over SSL?) redirects to a subdomain with plain HTTP.
Kinda weird setup!
Edit: okay, the subdomains also have SSL. I guess the random subdomain thing is to make sure it hasn’t been cached in a “this site has HTTPS” list. The HTTPS is needed, of course, to please the browser makers, as the parent says.
My browser (iOS safari) just takes me to the ssl version from that link, so “never ssl” seems wrong?

We (IPinfo) have a practice of adopting low-maintenance, high-utility services. Generally, we adopt websites that would have become defunct and run them as services.
Even though IANA says example.com is intended for documentation purposes and not as a service, I feel that it nonetheless serves as a service to the broader internet. I think there are some cornerstone services on the internet, regardless of the maintainers' intentions or their legal definitions.
For example, we ourselves sometimes have to recognize that we are not a standard API service. Considering that we expect to process 3 trillion requests this year, a major outage could take down a good chunk of IT systems everywhere. So, we invested in infrastructure to avoid outages. We then started adopting other cornerstone services and running them indefinitely because we might as well support the users who depend on them because we have infrastructure to support them and us.

I think what you describe is exactly right, it has organically become a service and it is maintained with that in mind.

Not to mention indefinitely. Any decommission, even decades in the future, will be messy.

Interesting, didn’t know that. Also I would have expected German and Hindi to be official UN languages given the number of native speakers in the world

Guess most of German speaking and Hindi speaking also know English.
Also open-source and self-hostable: https://github.com/httptoolkit/testserver. Lots of other endpoints too, full docs here: https://testserver.host/
As an example, depending on "man -w" not outputting anything to stderr: https://unix.stackexchange.com/questions/405783/why-does-man...
We removed the version and a few customers complained we broke their stuff.
The web page at example.com is maintained as a courtesy by IANA in order to explain the purpose of the example.com domain to wayward humans.
In the nomenclature of RFC 2119, one MUST NOT design computer systems that rely on the correct operation of an HTTP server at that domain. [0] Plus, it's _really_ rude to pound on a small-scale service being provided as a courtesy... go hit the home page of a tech megacorp (such as Microsoft or Google) or the status page for a major CDN (such as Cloudflare or Akamai) instead!
[0] I expect that someone here will want to pop up with a "gotcha" where they say something like "Oh, but IANA's email says that automated use is strongly recommended against, rather than prohibited and besides, they can't actually stop me from doing it!". To that, I reply "Sure, and standards-writers can't actually stop implementers that do the profoundly antisocial thing and do the things they MUST NOT. As any adult who's been paying attention to the world around them throughout their lives knows, there's only so much you can do to stop people who are very determined to be enormous assholes.".

Yes, I know it's not the example.com's fault, and it's a side effect of Hyrum's Law:
> This is not a service, avoid relying on it for testing and monitoring purposes.
Don't we all have a few fragile tests?
Likely for good reason, even back then there would have bound to be lots of misconfigured endpoints trying to access 1.1.1.1, so just blocking it at the earliest point possible kept at lot of the annoyance away. Nowadays, it’s an anycast address, so it’s slightly less bad.
But for me, old habits die hard.
Pinging such an address is inherently a troublesome practice. This address, like many public DNS servers (resolvers as well as root and authoritative ones), uses "anycast" routing methodology.
https://en.wikipedia.org/wiki/Anycast
Pinging an anycast address will yield a cornucopia of different results. Of course, people who naïvely "ping" a recognizable or easy-to-type IPv4 address get what they deserve, especially when they enshrine it into software, unit tests, or the LLM coughs up such tokens on their behalf.
Fundamentally, the question is "what do you really want to test?" by pinging a particular IPv4? Do you want to test Layer 3 connectivity? Test your ISP's backbone and connectivity? Test only your upstream router? Test the existence of ICMP in your stack and theirs?
... the possibilities are endless. Your router can do anything. Ping zombo.com.
Pinging a domain name could fail for a variety of other reasons, particularly if it's not a reliable site. Cloudflare's business is being reliable; few sites would be a better choice.

Looks like they removed this and instead just show all languages with no CSS animation now.
It still probably is as it is now. But there's better arguments to support localization than transitions.
Well, no. The purpose of the redesign is to move as much of the page content as possible into an external javascript file. There's no question of what parts of the page require javascript; the question is what parts of the page can be moved into javascript.

(I actually tried the select, share [sic], open in browser route, but for some reason I only saw opera as an option, not chrome, the browser I actually use for everything. Links still rule.)
I guess this is also done to prevent bad actors from abusing the fact that this domain is hit by people who might not know what they're doing (the ones copy-pasting code without reading it)
> Someone else could
When you own a domain, you can choose not to serve anything on HTTP/S, and still nobody can come and serve some other website on your domain, because they don’t control the DNS records.
It cannot manage a one page website. WTF
There are no page "aseets", no need for images, CSS, etc. It was a text-only website to test connectivity
iana.org forwards to Cloudflare, too
Fortunately the FTP server service still works
Without assistance from a third party
If it's been a sensible decision to use Cloudflare for some period of time then why did IANA wait until now
(Yes, I know they used Akamai in the past)
[0]: https://root-servers.org/
[1]: https://datatracker.ietf.org/doc/html/rfc6305.html
It's only responsible for root.zone, root.hints, .arpa and .int zones
AS112 is a volunteer project not a company
Years ago IANA started requiring a user-agent header
FTP access to root.zone remains
Given that they have gotten spiked by automated requests lately, aka agents, wouldn't this at least be respected by the big players?
Also, as they are using Cloudflare, wouldn't a discussion (or a note from IANA or CF) about how they configured CF request rejection and how one should love CF's flat rate static serving be appropriate?
Am I missing something?
eg If they put DNS, NTP etc on it... Likely billions per hour or something equally ludicrous.
Deluge is likely an exponential understatement.
which does appear to say that yes, IANA hosts this
(This was when it had the language scroll though, I think moving the extras to JS should have resolved that issue; maybe I was misremembering the details too.)
example.com is not a user-facing service. I don't want to disparage the designer, but it's not meant to be pretty. It's meant to be small so you can copy its response to an automated test or visually verify its correctness, or just out of the bandwidth consideration you'd still be serving it to billions of requestors, even if you insist it's not meant to be used that way.
example.com is meant to be legally allowed to be used in text such as "You visit a website (example.com) to browse the internet"
It is not meant to be queried by automated tests or used as a service.
It's 4.5x the size of the original. Which sounds bad, until you notice this means it's 2540 bytes and serves the explanatory text in 6x the number of languages. And it's now served with brotli compression, for a total of 1713 bytes. Or 334 bytes if you only request the HTML (which still has a usable page with the full English version of the explanatory text), like a basic scraper or a health check would. So for the vast majority of traffic, it's now half the size of the old version.
I notice it's been through several revisions, the pre-2025 version of the site most people are familiar with is 1270 bytes because it didn't make use of any minification, and it also triggered an unnecessary `/favicon.ico` request because it didn't use the trick to cancel the request.
It is not, in fact, _meant_ to be used that way.
Wait - using JS for dynamic content is understandable, but why using it for inserting a static SVG?
It's good to have a little color/flavor/spice in life.
The whole article reads like something put together with AI, so maybe it’s not too surprising.

Regardless, it’s a lot of code, so maybe better move it out to a pastebin/gist?
Isn't there a dedicated site called nohttps or something? NeverSSL? I just tried http NeverSSL, and it redirected me to an https page with a random hostname and an Amazon SSL certificate!
Does example.com still function this way, with http and no HSTS? I noticed that my Chrome browser was immediately redirected in the customary way.
Are you perhaps on an untrusted network which is spoofing that url to make it redirect somewhere else?
If this is a joke, it's over my head. If not, I'm not knowledgeable enough in this space to pass judgement, but that would seem crazy to me. Like the owner should consider a domain name change :)
Kinda weird setup!
Edit: okay, the subdomains also have SSL. I guess the random subdomain thing is to make sure it hasn’t been cached in a “this site has HTTPS” list. The HTTPS is needed, of course, to please the browser makers, as the parent says.
When a newbie learning programming sees this message, then this is a downer.
"Hello World from example.com [more info]"
A newbie shouldn't test their programs using example.com
IANA's email about why example.com changed
https://news.ycombinator.com/item?id=49915060
Even though IANA says example.com is intended for documentation purposes and not as a service, I feel that it nonetheless serves as a service to the broader internet. I think there are some cornerstone services on the internet, regardless of the maintainers' intentions or their legal definitions.
For example, we ourselves sometimes have to recognize that we are not a standard API service. Considering that we expect to process 3 trillion requests this year, a major outage could take down a good chunk of IT systems everywhere. So, we invested in infrastructure to avoid outages. We then started adopting other cornerstone services and running them indefinitely because we might as well support the users who depend on them because we have infrastructure to support them and us.
Instead it just seems to be an advert for ipinfo on a post about example.com?

And get I often get websites and ads in the language of the country my IP points to
