WW8Cloud 4. April. 2019, 15:00

The failures in our Cloud-system have been identified. A bigger update- and migration-process has been necessary.

During this process the cloud has been moved to its own separate server. WW8Cloud

We recommend switching all configurations where you use our WW8Cloud to this new server.

There still are some problems, but we will solve them in the days ahead.

The IT is back

30.09.2016 - 14:00


All systems working again, the Cloud services included.

System Emergency shutdown - back to normal

23.09.2016 - 16:30


The new identity management system (IDM) is working like a charm.

  • All clients in the institute are back to normal.
  • Most of the server services are working again, network shares and SVN repositories.

But one last thing missing are the cloud systems with calendars and filesharing. You can use the ww8Cloud again and access your files and personal calendar, but sharing and the institut calendars are still missing.

System Emergency shutdown - most systems back

22.09.2016 - 19:08


We lost our identity management system (IDM) today which is managing all our clients and user accounts.

A new IDM has been prepared and tested during the last months and has taken over now.

The bad news is all user accounts got lost and have to be recreated (except the ones of people with test accounts in the new systems). Everyone has to get a new password. I will send new temporary passwords by email if the email-address is available to me, unfortunately the email-addresses of all our users had been saved in the broken IDM.

All the clients in the institute (except for ww8-node1 and ww8-2029-1) are back to normal, home directories are available again.

Sometimes there is strange behavior when sshing around. Workaround is to kinit and source the ~/.bashrc . This will be solved tomorrow.

The SVN repositories are still not available, but will be back tomorrow too.

The Ownclouds (owncloud and fass-cloud) are not working, the need a little bit more tuning, hopefully they will be back tomorrow afternoon too.

The student laptops which have been borrowed by some students (Bergmann and Monnavari) will loose the ability to login during the next weeks and have to be returned to the institute to be configured for the new IDM.

System Emergency Shutdown

22.09.2016 - 11:19


All our systems will be shut down for at least one our. After this all passwords have to be reset.

  • Home directories and Login to clients in the institute will not be available.
  • SVNs will not be available.
  • Owncloud and other services will not be available, maybe for an even longer time.
  • The cause of all these troubles is our Certificate system which died yesterday afternoon. Certificates can not be renewed because of some internal problems.

The fastes way to solve the problem is to just set up a new one.
