For me, at $work: on Friday, my experiments agreed with choroba's traceroutes above, where 204.16.243.219 was causing a hard-stop whereas 204.16.243.217 was skipping one but eventually making it to a perlmonks server. But today, whichever perlmonks IP I am tracing to, it is going through .219 but is connecting.

Over the weekend at $home, I could never get a connection using my home network. But if I took my phone off wifi and tried to connect with my phone's data provider instead, it could get a response and let me read posts.

And when I try https://www.isitdownrightnow.com/perlmonks.org.html, they say it's been down "~6 days" at this point.

It looks like it's highly dependent on where you are trying to access from whether or not you'll be able to get a route to a perlmonks server.
