This will affect Jabber itself and all transport services, and also this website. And it will take place during the next 24 to 48 hours. Please be patient and expect some service outages. We changed the TTL of our DNS zones to 1 minute but nevertheless it could be that your client still looks for the old server. You might need to relogin to the Internet and/or restart your client.
We will be back here when everything is moved. Until then you also can reach us on Twitter, where a link to this post will also be posted.
