Itʼs not responding on IPv6. Probably because it doesnʼt have that
IPv6 address configured, which its admins will be doing at some
point. If you'd left it longer you'd have seen it trying IPv4, and
failing, which is an Emacs problem.
The only workaround I can suggest in the interim is to use its IPv4
address explicitly in package-archives, ie
(setq package-archives '(("gnu". "https://209.51.188.89/packages/")))
which will probably elicit warnings from the network-security-manager,
but in this particular case they're harmless.
