Deutsch Dear Sir or Madam,
we would like to inform you about changes to the maintenance windows for the Nvoice for Skype for Business platform:
Due to the current situation, there is an increased maintenance effort for our supplier in order to adapt the platform capacities to the increasing demand. In addition, the strong customer demand for short-term onboarding domains must be entered into the certificates. For stability reasons, certificates are only entered in maintenance windows.
Therefore, in addition to the regular maintenance windows, another maintenance window will now take place:
- Weekly, every Saturday from 6:00 p.m. to midnight
This regulation initially applies until the end of June 2020.
We apologize for any inconvenience this may cause.
Kind regards,
the NFON Team
