It is by the far the longest outage for a major platform in recent memory. Shouldn't a big company have better processes? The outage meant that they couldn't authenticate to the premises and get inside. The access cards that Facebook use to physically enter its premises were also dependent on the internal systems working properly. The only solution was to physically go to the data centres and refresh things from there - but there was a problem with this too, according to a now-deleted post on Reddit believed to have been posted by a Facebook staff member.

Then when staff tried to sign-in to third party apps to communicate, if they used the 'Log In with Facebook' option they discovered this was down too.

It took down Facebook Workplace, the internal communications platform used by its staff, according to numerous reports. Unfortunately, it seems that Facebook was using the same network for staff to access the network remotely, meaning that the outage prevented them fixing the outage. Normally it would be quite straightforward to fix this kind of outage - you start advertising where your servers are and routers begin connecting to you again.
