Yet small remark about security:
As inaccessibility workaround you can use (as mentioned on
referenced topic
discussion):
- Archive.org snapshots (wit some delay of binary release)
- Public Proxy
- Public VPN
- TOR browser
With exception of first one, all methods can be quite dangerous!
So every time double check on download page of installation binary:
1. Good Server address:
physics.princeton.edu
not physics.princeton.edu.me or physics.princeton.edu.ru etc.
2.Encrypted connection with valid certificate
Don't click through warning about problems to access page.
Usually small
lock picture as prefix of URL. Most modern browsers show full url
only
after click on address bar after page load.

Attackers can try to redirect your request to page to unencrypted
channel.
And then downloaded binary can by modified on fly and infected
with malware.
Highest risk is on TOR network. Quite high percentage of TOR exit
nodes modifies
on fly all (!) executable binaries downloaded via them. (But of
course they can not
do it on properly secured https channel.)
Risk is higher on older not updated and patched browser on old
unsupported or
not updated OS as Windows XP.

Zdenek, and others,
your immediate problem may be solved by use of the *Internet
Archive*, and, in particular, the Wayback Machine. Try looking
at
https://web.archive.org/web/20211207214103/https://physics.princeton.edu/pulsar/K1JT/,
which seems to be the most recent snapshot (at least as of today).
The base problem is as described at

checkpoints:

This troubles are long term - several months or more - in past
I believed that referenced URL from other sites is outdated...

Hello,
let me report that web
http://physics.princeton.edu/
is inaccessible from (and only from!) big part of Europe.
See result of tests(bottom side of results table):
https://www.uptrends.com/tools/uptime?toolRequestGuid=f1016efc-09d0-401d-8e6f-1e82dfaeba88
Reason is probably misconfiguration of some kind of DOS IP
filtering
for this web. Other webs as for example:
https://phy.princeton.edu/
seems to be OK.
If you are not right person to receive this report, please
forward it to correct IT admin responsible for administration
of web on domain
physics.princeton.edu
Sincerely Zdenek Hladik
