Hello Martin!
You are having a strange and unexpected experience with the CDN, I only see this happening if your network is redirecting traffic to GitHub endpoints.
Here are some techie stuff that might help you and your network team diagnose the issue if it persists on your end.
Currently if you make an HTTP request (non HTTPS), it will respond with a permanent redirect to HTTPS endpoint, so your result very strange for us.
I have just checked and I am getting the expected values:
- HTTP - 301 redirect, invalid resource address
- HTTPS - 404 not found, invalid resource addressCode:$ curl -i http://speed.ext.net/ext.net/3.3.0
HTTP/1.1 301 Moved Permanently
- HTTP - 301 redirect, valid resource addressCode:$ curl -i https://speed.ext.net/ext.net/3.3.0/
HTTP/2 404
- HTTS - 200 found, valid resource addressCode:$ curl -I http://speed.ext.net/ext.net/3.3.0/extnet/extnet-all.js
HTTP/1.1 301 Moved Permanently
Check again, if you still get this error, check from other networks and check with your network if you are having any redirects to GitHub resources.Code:$ curl -I https://speed.ext.net/ext.net/3.3.0/extnet/extnet-all.js
HTTP/2 200
Currently, speed.ext.net should be resolving, DNS-wise, to the following IP addresses:
Queries to one of those IP addresses should show the following headers; different headers suggest tampering with your connection:Code:;; ANSWER SECTION:
speed.ext.net. 98 IN CNAME extnet.github.io.
extnet.github.io. 3010 IN A 185.199.110.153
extnet.github.io. 3010 IN A 185.199.111.153
extnet.github.io. 3010 IN A 185.199.108.153
extnet.github.io. 3010 IN A 185.199.109.153
While the output above is correct for current state, this may change without notice in the future, so you should use these headers as base within the next few days but there's no guarantee the HTTP headers will look the same, say, in year 2022 or later.Code:$ curl -I http://185.199.110.153/
HTTP/1.1 404 Not Found

Hope this helps!
The http URL's will automatically redirect to https.
The following URL should return a 404. That is the expected result.
https://speed.ext.net/ext.net/3.3.0/
Because, there is nothing at that endpoint.
If you change to point to a.js
file:
http://speed.ext.net/ext.net/3.3.0/extnet/extnet-all.js
Then it should automatically redirect tohttps
:
https://speed.ext.net/ext.net/3.3.0/.../extnet-all.js
Hope this helps.
