So, three nameservers out of seven for the pubmed.ncbi.nlm.nih.gov are broken. If you try to look at the web site, you stand a 3/7 chance of encountering something that is broken.
The nameservers have the following addresses:
$ host ns.nih.gov
host ns.nih.gov has address 128.231.128.251
$ host ns2.nih.gov
host ns3.nins2.nih.gov has address 128.231.64.1
$ host ns3.nih.gov
ns3.nih.gov has address 165.112.4.230
We can see that the addresses for the first two both start with 128.231 and might guess that they are relatively nearby to each other. This can be confirmed using traceroute. Go ahead and open a terminal and try it out!
traceroute 128.231.128.251
traceroute 128.231.64.1
for me, the paths, the sequence of routers between me and those addresses look broadly the same.
The other one is different,
traceroute 165.112.4.230
it goes a totally different way. So whatever problem is happening is not limited to a single site or datacentre.
Now we can turn to RIPE for some help.
Let us inspect the last address, https://stat.ripe.net/widget/bgplay#resource=165.112.4.230
This is very peculiar. Notice how that network is announced from two different places. And there seems to be a partition, they are not (visibly) connected to each other! This is not normal. I attach a screenshot. There is also some volatility, shown as path changes, the yellow bars at the bottom.
Looking at ns.nih.gov, https://stat.ripe.net/widget/bgplay#resource=128.231.128.251
this appears more coherent, but volatile. The network was withdrawn about 45 minutes before I took the second screenshot, about an hour ago. And then re-announced.
RIPE's BGPPlay is very nice, you can time travel and replay this incident as observed from the Internet. It takes a bit of background knowledge to decode what is going on though.
Someone is doing networking... Badly...

An incredibly technically complex #backdoor in xz (potentially also in libarchive and elsewhere) was just discovered. This backdoor has been quietly implemented over years, with the assistance of a wide array of subtly interconnected accounts:

The timeline on this is going to take so long to unravel
Ho lee shit.
The AP has found that the number of deaths caused by the police in the US is SIGNIFICANTLY higher than thought because they're not always reported as being "officer-involved."
❝
The investigation found that between 2012 and 2021, more than a thousand people died after police use physical force that was not intended to be lethal. That includes batons, stun guns, physical restraints, and chemical agents. The oldest victim was 95 and the youngest 15.
Only 28 of the officers were charged.
The Police role was only cited in about half of the cases, meaning that many more Americans have died at the hands of the police than was previously known.

"These refusals come at a huge cost to individual researchers. Visa applications require scientists to be studious with paperwork, commit often large sums of money and make several trips to embassies that are sometimes outside their home country. My experience left me feeling demoralized, embarrassed and insulted by the implication that I and people like me couldn’t be trusted to attend a conference without outstaying our welcome."
"(...) Monet’s “Boulevard des Capucines” (1873), the teeming vista of a city that knew itself to be the capital of the 19th century.
Monet painted this from the very gallery where the First Impressionist show took place, the studio of photographer Nadar. He thus challenged photography on home ground, assimilating its plunging viewpoints, sharp angles, blur of movement, while in the painterly blending of small flickering strokes he evoked urban experience as a web of light and atmosphere."

It's not clinched yet, but of the 534 members of the congress who chose to pass on a once-in-history opportunity for exploration, 24 are still alive. And the actuaries don't have _great_ news for those who remain.
Meanwhile, the Voyagers have another 1-6 years of science mission left, and could well keep returning engineering data until 2036, at which point they'll be too far away for the DSN to communicate with them.
So... I'd say it's game on, really.
I went down a Voyager rabbit hole again. And I came up with a factoid that entertains me.
The original Grand Tour program was canceled in late 1971, due to congressional pressure over cost. Voyager was the cheaper mission to just Jupiter and Saturn.
Voyager and its team are incredible, and they managed to pull off the entire grand tour anyway, and then 34 years and counting more science after that.
There's a good chance Voyager might outlive the entire congress that killed the grand tour.
