I have installed macports many times, so I’m not naive about what to

You have a somewhat poor connection to rsync.macports.org, which is (as
implied by the canonical name) in Germany. Even assuming that the lost
packet is an artifact of the ^C and hence ignorable, the TTL on the
replies says that you're 24 hops away and the times are long and very
noisy. Are you in Australia? New Zealand? The Maldives? An
over-subscribed dialup link in a flat in Berlin?

That's what one would expect from a VERY poor link, something much worse
than your ping results would imply. Or from a path that simply isn't
letting the rsync traffic through at all. This is absolutely a
networking problem.
If you've been able to sync or selfupdate on the same link before, it
isn't something inherent in your local network. If you were running
something like LittleSnitch or LuLu you'd know it and probably get an
alert regarding the blocked traffic or at least have experience with
mysterious outbound blockages.
My *guess* is that this is outside of your control and that it will
clear up in a relatively short time: hours to maybe a day or two.
There's been substantial weirdness in global routing this week (A
Nigerian ISP hijacked Google's & CloudFlare's traffic and aimed it at
China by way of Russia, where it was blackholed. Not kidding.) It would
not be a surprise to see a lot of transit providers, particularly
inter-continental ones, making lots of new tighter route filtering
policies on an urgent basis all at once and relying on the network to
eventually stabilize after a period of strange behavior. Apart from the
"oops" in Nigeria, there's been some press recently about China Telecom
doing sketchy things with their routing to make networks paranoid.
