Hi Daniel,

Hmm,
$ wget http://www.ctan.org/tex-archive/systems/texlive/tlnet/tlpkg/texlive.tlpdb
..
$ wget http://www.ctan.org/tex-archive/systems/texlive/tlnet/tlpkg/texlive.tlpdb.sha512
..
$ wget http://www.ctan.org/tex-archive/systems/texlive/tlnet/tlpkg/texlive.tlpdb.sha512.asc
..
$ sha512 -c texlive.tlpdb.sha512
texlive.tlpdb: OK
$ gpg --verify texlive.tlpdb.sha512.asc 
gpg: assuming signed data in 'texlive.tlpdb.sha512'
gpg: Signature made Thu 30 May 2019 08:39:33 AM JST
gpg:                using RSA key 0x4CE1877E19438C70
gpg: Good signature from "TeX Live Distribution <tex-live at tug.org>" [full]
Primary key fingerprint: C78B 82D8 C795 12F7 9CC0  D7C8 0D5E 5D91 06BA B6BC
     Subkey fingerprint: D8F2 F860 57A8 57E4 2A88  106A 4CE1 877E 1943 8C70
$

So I can only assume that you are hitting the servers consistently when
the servers are being updated (rsync). Any other explanation would be
surprising to me.

If you hit that again, can you try the above? 
And retry 1h later or so?

Thanks

Norbert
