Blog from April, 2010

On Thursday 29 April 2010 between 07:00 and 08:00 local Bremen time servers and network components will be updated.

Server and network operations will be unreliable. Expect unavailable servers and sudden downtimes of services without prior explicit announcement.

If you have to work on files stored on the server during that time, then before the maintenance hour copy the respective files to your local hard disk, work on it locally, and after finishing your work and after the end of the maintenance interval, copy them back onto the server.

For more details on the maintenance hours see the Maintenance Hours page.

At around 16:07 on April 19, 2010 Jacobs Email was temporarily unavailable. This also affected the web interface, Outlook clients, and other email clients.

The servers are back online, no emails were lost.

Several Jacobs members received emails on April 17, 2010, with a subject line of "Jacobs University - Email Services - Neu SSL Sever Rangliste - Must Read."

The content was pure nonsense, practically incomprehensible, refered to a non-existing department, and contained a link to a web server outside Jacobs university, asking for username and password.

This is an attempt to get Jacobs' users' accounts and passwords.

The link to the external web site is now blocked on our firewall.

If you did enter your information on that site, you should IMMEDIATELY change your Jacobs password in the CampusNet system.

The only reliable protection against such phishing attempts is the consciousness of the recipient. Acting according to the General Policy Governing the Appropriate Use of Computer Resources policy also helps: "You must not share your password with anyone else"

Hints to detect forgery and phishing:

  • No-one legitimate would ask to enter a password on a non-Jacobs site.
  • The remote website is not a Jacobs web address.
  • The content refers to the non-existent service "Jacob University Helpdesk Security Department".
  • The content is gibberish (intended to bypass anti-spam measures).

If similar cases appear in the future, please submit them including all headers via email to itsupport@jacobs-university.de, so that appropriate actions can be taken.

According to new regulations by the Bundesministerium für Post und Telekommunikation, sending emails will cost 1 cent per email. Receiving emails will still be free. See E-Mails sollen Porto kosten! (in German) for details.

This will dramatically reduce spam, enable verification of senders, and preserve IT equipment and staff job satisfaction.

To comply with this new federal regulation, sending emails for free will stop at Jacobs University today on April 1st, at 16:00. This is an automated process and can not be stopped. There can be no exceptions. Apologies for any inconvenience this might cause.

To compensate for the administrative overhead and technical measures, Jacobs University will charge 1,4 ct per email sent. Pre-payment options will be available soon. Discussions with Financal Aid for appropriate packages are underway.

Overpayment will not be refunded, but collected until next April 1st. You can vote on, where the University will send overpayments to:

Update Apr 1st, 16:40

Due to the short time frame given, implementing the new cash-in system could not be achieved today. Deployment has to be moved to one of the next April Fools' Days. Any money cashed in so far was spent on sending out emails today, there are no leftovers.

Happy Easter!
