The web server on fafner has been closed down. Its tasks has been transferred to a new host, and in general the transfer should not make a difference for the general public.
If you have a blog/Wordpress site, you’ll get a new login and password shortly. If you have a static web site, you should already be aware of the new login tokens. If there is anything amiss, do not hesitate to raise the issue with MEB IT thru the usual channels.
