it jsut struck me, is there a list somewhere somebody maintains of "free" airport wifi networks that just plain don't work, block ssh out, appear to be blocked by the outside world in general?
Not asking for a friend (yes, using my phone as hotspot in TPE at the moment), and I have encountered a few more that should be added to such a list.

Since the original came out, I have made updates here and there, and added references to some newer material.
You could see "EU CRA: It's Later Than You Think, Time to Engineer Up!" https://nxdomain.no/~peter/eu_cra_its_later_than_you_think_time_to_engineer_up.html as a further development in response to the real world (or at least the EU parts) moving forward.

Friends,
It feels like it was in a different century, but at the beginning of the #russia-#ukraine full scale war I speculated that you could predict development in conflict based on the intensity of attempted #cyberattacks, see https://nxdomain.no/~peter/Predicting_developments_in_real_world_conflict_from_patterns_of_failed_logins.html. The data now covers four years.
I ponder whether it's worth using the data (linked in the article) to see how these things correlate.
I'd love to hear your thoughts.

One of the several times I was asked to do a talk about why I'm an #opensource enthusiast with a particular fondness for #OpenBSD, I wrote "Recent and not so recent changes in OpenBSD that make life better (and may turn up elsewhere too)" https://nxdomain.no/~peter/recent-and-not-so-recent_changes_in_openbsd_that_make_life_better.html in 2021.

if you interrupt my typing a passphrase or entering a short lived one time code for authentication to ask me anything, included but not limited to whether I would recommend this site to others, you have ensured that I will only ever revisit your site only if no less painful option exists, and most certainly that I will not recoommend your site or service to anyone.
