Problems sending emails because of LDAP outage

STATUS: Status/green.gif

2014-12-02: 16:15
Set status to green as we had no other problems.
2014-11-30: 23:15
We have reconfigured dovecot to use another ldap server. Currently it looks that sending emails with dovecot or roundcube is working again. But since we do not know the cause of the outtage it could be possible, that this newly configured LDAP server could also crash.
2014-11-30: 16:50
One of the main LDAP Servers (ldaps-rz-2) from the informatik dienste, used to authenticate the sending user, is not available anymore.

Maintenance work on D-ITET's central IT infrastructure

STATUS: Status/green.gif

2014-11-22: 14:00
All services are back online.
2014-11-22: 10:00-16:00
To keep our systems up to date with the newest software and security releases, we need to update our servers on a regular basis. For this reason we are going to install latest Oracle patches on our main servers. The servers will be rebooted during this maintenance.

To prevent data corruption/loss please do the following:

Our webmail server "roundcube" is currently down due to maintenance.

Swisstime outage

Due to a new Linux kernel vulnerability all of our workstations, compute cluster servers and service servers will be rebooted.

Swisstime outage

STATUS: Status/green.gif

The switch has been replaced and reconfigured.

OpenSSL Heartbleed vulnerability

STATUS: Status/green.gif

2014-04-07: 21:00
we got aware of a OpenSSL vulnerability in OpenSSL's support for the TLS/DTLS Heartbeat extension. Memory from either client or server can be recovered by an attacker. This vulnerability might allow an attacker to compromise the private key and other sensitive data in memory.
2014-04-08: 06:30
Relying on the updates of our used distribution we rolled out the update and had at this time already patched versions on all vulnerable servers.
2014-04-10: 08:00
Updates were rolled out also on Clients side.
2014-04-14: 12:00
OpenSSL certificates are replaced for previously affected services on the vulnerable servers.
2014-04-16: 16:00

Informatikdienste announce that they also patched all relevant services and advice customers to change the password. We confirm that this step is strongly recommended. Note in particular that the vulnerability was already exploited since November 2013 to collect passwords, session data, private keys, etc.

No Emails accepted from webservers

STATUS: Status/green.gif

2014-04-14: 14:00
The plugin which caused this malicious behavior has been deactivated. Email connections from the webcluster work now as intended.
2014-04-13: 18:00
A webform has been missused to send spam over our infrastructure. In order to make sure this does not happen again until we investigate the case, all emails sent from our webservers will be rejected. Unfortunately some scripts do not realize this rejection and create a success message.

We appologize for this.
