Overleaf

A new filter is being implemented in the TU Darmstadt production system. This should not result in any restrictions for users.At the same time, some accounts will be deleted because the licence scope has been exceeded.Affected users were informed of this two weeks in advance.

Scheduled Maintenance for the ShareLaTeX Service
On 09/30/2025, an update will be performed on the ShareLaTeX server between 8:00 AM and 9:00 AM.
Impact:
The service will be temporarily unavailable during this time.
We kindly ask for your understanding.

Die TU Darmstadt hat heute alle Accounts aus dem alten Testsystem entfernt, da das Testsystem aktuell neu aufgesetzt wird. Das System hat eine automatische E-mail versendet mit dem Betreff "Overleaf security note: account deleted".
Die produktiven Daten auf sharelatex.tu-darmstadt.de sind davon nicht betroffen. Diese sind weiterhin vorhanden.
Es betrifft nut das Testsystem, auf dem sich ein altes Backup befand. Die E-mail kann ignoriert werden. Wir entschuldigen uns für die Unannehmlichkeiten.

The current LuaTeX is not functioning yet, but in general, the necessary security could be established through the implementation of containerization.

RWTH Single Sign-On login ist not possible at the moment.
Existing sessions are not affected.
We are working on fixing the problem.

The problem has been solved.

There are currently disruptions to RWTH Single Sign-On. After entering your login details, the screen loads and then an Internal Server Error appears. This affects all services that use the RWTH Single Sign-On login.
The specialist department has been informed and is working to resolve the issue.

The problem has been fixed.

Es gibt aktuell eine Störung beim Upload von Dateien in ShareLaTeX. Es ist weiterhin möglich txt-Dateien hochzuladen, andere Dateiformate funktionieren aktuell nicht. An der Problembehebung wird aktuell gearbeitet.

Die Störung wurde behoben. In der Overleaf Instanz in Kooperation mit der TU Darmstadt ist es wieder möglich, alle Dateiformate in ShareLaTeX hochzuladen.

During this period, the routing of the previous XWiN routers (Nexus 7700) will be switched to the new XWiN routers (Catalyst 9600). These routers are essential for RWTH's network connection. This changeover also requires the migration of the DFN connection, which is switched redundantly to Frankfurt and Hannover, and the RWTH firewall to the new systems.
There will be complete or partial outages of the external connection during the maintenance window. All RWTH services (e.g. VPN, email, RWTHonline, RWTHmoodle) will not be available during this period. The accessibility of services within the RWTH network will be temporarily unavailable due to limited DNS functionality.

Der Uplink nach Frankfurt wurde erfolgreich auf das neue System geschwenkt.

Umbau des Uplinks nach Hannover beginnt.

Uplink nach Hannover auf das neue System umgezogen.

BGP v4/v6 nach Frankfurt und Hannover sind nun über die neue Routern funktional.

Es stehen noch ein paar kleinere Nacharbeiten an.

Wartung ist abgeschlossen. Der Datenverkehr läuft nun vollständig über die neuen Router!

Problematik mit der Anbindung zur Physik identifiziert, Lösung erfolgt morgen früh.

There is currently a fault with the login process for RWTH employees in the Overleaf ShareLaTeX version, which is provided as part of the cooperation with TU Darmstadt. It is currently not possible to log in via SSO access. The disruption is expected to last until next week.
The use of Overleaf via Sciebo is still possible. Further information can be found in the Help ITC: https:
help.itc.rwth-aachen.de/service/b07d844d198c499e86d893fd87ed1984/article/c22c858eee0344ab9f6241e51080d608/

The malfunction has been fixed. Login via https:
sharelatex.tu-darmstadt.de/saml/login is possible again.

This evening around 20:25 - 21:00 there was a performance low in the SSO service and was checked by the specialist department during this time. The problem has been solved and fast logins without waiting times are possible again.

Nach der Störung vom 16.12.24 bis 18.12.24 mussten Konfigurationsänderungen in Overleaf eingespielt werden.
Das hat zur Folge, dass teilweise per Default in ShareLaTex nach der Konfigurationsönderung die Tex. Version 2017 verwendet wird. Hierdurch sind Projekte zunächst nicht kompilierbar. Nutzende werden gebeten, die Tex Version 2023 oder 2024 auszuwählen. Danach funktioniert die Rekompilierung wieder.

At the moment, single sign-on and multi-factor authentication are sporadically disrupted. We are already working on a solution and ask for your patience.

Since July 2, 2024, the RWTH Single Sign-On (SSO) and the login of all SSO-connected services is protected with multifactor-authentication (MFA). In addition to an individual password, users must now enter a second factor when logging in. The second factor must be generated in Selfservice [1] via the Token Manager. Further information can be found on IT Center Help [2] and the IT Center Blog [3].

Unfortunately, the login via the RWTH Single Sign-On and thus into the connected services is currently only successful in individual cases.
If you receive an error message, please try to log in again in about an hour.
People who are already successfully logged in are not affected by the disruption.

The servers are currently at full capacity. We therefore ask you to try to log in at a later time (approx. in one hour). We are working on a solution to the problem.

Through various measures, which have significantly increased the overall performance of the servers, the loading difficulties and login problems were resolved around 3 pm.
For the time being, the message remains as a note, as we continue to monitor the load on the system.

The login to the RWTH Single Sign-On is stabilized. For this reason, we are ending this notice.
