Yes, my server would be one of those who cannot reach jabber.ccc.de any more. I did not get around to turning it on yet, I need a software upgrade for that. I understand the need for extra security but enforcing it right away without giving fellow operators time to upgrade as well will only

I second this a little bit. In my case I need to upgrade from Debian wheezy to jessie to get PFS, so there is more work involved. And I'd expect a decent number of servers to be in the same situation. Jessie came out in April, so it's not brand new. But it is still fairly recent and you can't

Had upgraded from Wheezy's ejabberd to Jessie's in a week the latter was released and can say that it was not that hard. Now ejabberd is relatively up-to-date and works great. The configuration format changed to YAML, but ejabberd is shipped with a conversion tool, which converts old config

Excuse me, but i dont understand your problems, for example my public jabber server ( https://xmpp.net/result.php?domain=jabber.plitc.eutype=client ) runs PFS for a long time and it's just a cheap freebsd jail with always the current prosody port ( http://www.freshports.org/net-im/prosody/ )

why not allow 2048 for now with the prerequisite that all server may move to 4096, if we can actually agree on it. Some people may also need to purchase new certs anyways, so at least they have a heads up. but that's just me.. I just had a 2048 last year before renewing and just so happened to do
