it just 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? (one or more of, other criteria fine too)

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.

Please boost for reach.

as in, even https://whatsmyip.com was not reachable from the TPE free wifi.

I have a few others in mind for such a list, including a few that do not appear to have a DHCP service but a very strong signal

@pitrh usually ssh on port 53/tcp works fine in ugly managed WiFi networks 😉
@pitrh Spoofing free WiFi SSIDs is a common attack vector at airports, so be careful with those.

@alda yes, but they would need to provide some semblance of working access to somewhere, wouldn't they?

These clowns, for whatever reason provided only radio signal, name resolution but not actual reachability anywhere I tried.

@pitrh a list of working WiFi networks with a timestamp *when* they last worked would probably be more useful and shorter.  
I have slightly more success with lounge wifi networks...
