[Guillaume ROMAGNY <guillaume AT cacert.org>]

Hello everyone,

Wiki part (I am not blaming anyone...)

after a wiki migration or wiki security fix (I cannot say), the wiki
server never stops the HTTP connexion so I guess the server is
overloaded some way (I can't say why). I have to click on the Firefox
button "stop loading this page" so the page stops to load. the issue
lasts for months at least.

We never had this issue with moin-moin in the old days. Sorry, no idea
to propose you.

Best regards,

Guillaume
