I am posting partly to prevent freezing - but on this occasion perhaps I have something useful to say.

@JourneymanGeek concerning this suggested edit: superuser.com/review/suggested-edits/1177611

I have noticed some dead link from the domain pps.jussieu.fr so I checked whether there are some on other sites in the network.

The links to Polipo were easy to fix - the new URL is https://www.irif.fr/~jch/software/polipo/.

So I suggested edits in places where I saw such links. In your answer there is one other link which no longer works - I wasn't sure what would be a suitable replacement, so I left that one untouched.

(I am aware that this is unrelated to the purpose of this room - but it was a place where I was able to reach you; and having here a message with some actual content is slightly better than messages which are posted just to prevent freezing.)

@MartinSleziak That answer makes me sad :D

Most of the services involved are dead so I'd be inclined to delete

And I quite miss sixxs, they were a really 'easy' flexible IPV6 tunneling option
