Sfax has addressed the outage and faxing functionality is back to normal: you should no longer see errors when accessing or sending faxes, as well as when saving them to a client's documents folder.
Faxes sent during the outage will be received after being processed by Sfax: they're working through the backlog to ensure any pending transmissions are delivered to their intended recipients.
