Reports of troubles accessing Facebook by Orange Mobile customers suggest that Facebook has started to ban a significant a mount of IPs from the Orange ISP IP Pool. This highlights the problems associated with using IP as a means to block trouble makers – quite often the IP used belongs to others not just the abuser.
The general user base showing ignorance of the technical abilities of the two companies have already been complaining to Orange. Yet quite clearly Facebook is the one with the power to block access to its site by IP.
The two companies are however working together to hopefully restore connectivity to the service.
