From tracepath, it seems to stop at some "RIPE" server[1]:
--8<---------------cut here---------------start------------->8---
[18:02 ~/bs]$ wl-paste 
11:  cr-tub2-be10.x-win.dfn.de                           102.352ms asymm 10

14:  no reply
--8<---------------cut here---------------end--------------->8---

FWIW:
[1] whois 141.80.238.11 >> whois.141.80.238.11.txt
and copying some lines from the less view:

--8<---------------cut here---------------start------------->8---
less whois.141.80.238.11.txt
[18:05 ~/bs]$ wl-paste

I guess their server would be the one that couldn't get anything from
where my wget failed:
--8<---------------cut here---------------start------------->8---
Connecting to issues.guix.gnu.org (issues.guix.gnu.org)|141.80.181.40|:443... connected.
HTTP request sent, awaiting response... 502 Bad Gateway
2022-07-25 15:05:57 ERROR 502: Bad Gateway.
--8<---------------cut here---------------end--------------->8---

How hard would it be to set up some kind of fail-over at issues.guix.gnu.org
(which presumably resolves ok internally) to say, e.g.

--8<---------------cut here---------------start------------->8---
    We know issues.guix.gnu.org (141.80.181.40)
    has been down since YYYY-MM-DD hh:mm:ss, sorry.
    Admin notified YYYY-MM-DD hh:mm:ss who replied:
    
    Fix ETA: ...
--8<---------------cut here---------------end--------------->8---
I.e., IWBN to get something informative from gnu rather than some net
error code :)

Is there an easy way to determine on the serving server how it is
responding to requests from the internet and switch/restore if down/up?

Or would you have to resort to some kind of periodic selfie-probe via
SSH/VPN to a cooperating mirror server?
(amateur idea :)

BTW, a good solution for informatiive status in place of error codes
might be applicable to other server stoppages and problems too, n'est-ce pas?
