Planned service windows
Service windows
We use maintenance windows to apply security updates and to continuously test both hardware and software, as well as to ensure that everything functions correctly in the event of unforeseen incidents. Therefore, on the announced dates, minor disruptions to internet connections, IP telephony, and mobile telephony services may occur between 22:00 and 02:00.
We apologize for any inconvenience this may cause.
Please note
If you experience issues with your internet connection after a maintenance window, please first try restarting your router before contacting support.
