Affected: all users of chat.gwdg.de
Impact: Display problems due to caching

The maintenance of Rocket.Chat has been completed.

Due to an error during the process, an unconfigured service web page was briefly displayed.
service web page was displayed that did not allow logins and contained the default Rocket.Chat logo. Although the condition lasted only briefly, browsers and clients of users who were online during the maintenance may have cached portions of the web page. This may result in the website logo being displayed incorrectly or user names in the service being displayed only as user IDs instead of first and last names.
The caches of browsers and clients do not normally hold this content indefinitely, but currently they do not. Indefinitely, but currently it is not known how long the storage and thus the impact would last.
