Failure of part of the network connection
This morning, Friday, 22.10.2021, the network connection from internal to the data center was disrupted for a few minutes.

Currently, there is still a problem with WLAN, so that WLAN connections cannot be established at DESY at the moment.

Connections from outside to DESY do not seem to have been affected by the problem.

As soon as more details are known, we will inform you.

We are working with the highest priority to resolve the problem.

Trouble caused by: Is under investigation.

Login to Sync & Share partially not possible
Since a few days, there are intermittent problems with the login to DESY Sync & Share (among others sas.desy.de), if the network connection is established via the gateway computer bastion.desy.de.
In such a case, an error message appears indicating that too many login attempts are being done via an IP address at this time and access is therefore blocked for this IP address.

A solution to the problem will be implemented this afternoon.

Trouble caused by: A security mechanism of the service to prevent so-called brute force attacks (i.e. a very high number of login attempts).

In urgent cases, please contact the copy service (kopierzentrale@desy.de) to have A0 posters printed there.

We are in contact with a service provider to have the hardware defect on the device fixed soon. However this will probably take a few days.

Currently we observe problems when editing web sites using the Atlassian Wiki Tool Confluence (https://confluence.desy.de). This means, if a page is saved you won't get the same page later again but some random previous version of it, so changes are lost.

Therefore, please check the page content of a revised version with the content of the updated version before you save the page.

We are working on a solution to this problem together with the manufacturer.

Regular Update of the Zoom App
Users who have installed the Zoom app on their computers to use the Zoom video conferencing service should ensure that they regularly update this app to the latest version.

The reason for this is that the minimum requirements for the Zoom apps are checked at regular intervals in order to guarantee all security-related updates of the conferencing tool on all computers.

If the app is no longer sufficiently up-to-date, you will be prompted to update. Without installing these updates, it will subsequently no longer be possible to use the Zoom App.

We therefore ask you to always keep your installed Zoom App up-to-date when prompted by it and to perform the necessary updates.

Command 'python' executes python3 on CentOS 8 and Ubuntu 20.04 systems
As of Monday, 11.10.2021 10:00h, the "python" command will be added on CentOS 8 and Ubuntu 20.04 systems and will execute "python3".
This will default to the current python version and configure the python command on Ubuntu 20.04 and CentOS 8 using the same logic as on previous OS versions.

With this change, python2 will _not_ be uninstalled, should it be present.
python2 could still be called via "python2". The "python3" command will also remain available.

Since python2 will not receive security support since 01.01.2020 and is therefore End of Life, it is strongly advised to use python3 exclusively anyway.
python2 scripts can be ported automatically via "2to3". More information can be found at https://docs.python.org/3/library/2to3.html.

Questions about this can be sent to linux@desy.de.

Reason for the News: Standardization of the python configuration.
