As an experiment, I've switched apt sources from "deb.debian.org" to

Please, report it as a bug unless those, who are running that mirror,
are aware and working on the issue and unless your ISP has aggressive
transparent HTTP proxy.
I expect that apt uses the mirror that may be obtained from
dig -t SRV _http._srv.deb.debian.org.
(see <https://deb.debian.org/>). Check modification time of Release
and Packages files in appropriate sections.
This command doesn't return anything useful.
You probably meant it to be:
dig -t SRV _http._tcp.deb.debian.org.
Apparently, "deb.debian.org" is a CNAME to the Fastly CDN.
I don't think I can dig up real hostname of a problematic mirror this way.
