    Some other things it could be:

    - it's a planned outage of some internal system for an upgrade/patching/DR exercise

    - it's an unplanned outage of some internal system because some planned change to something it depends on went awry and had an unanticipated impact

    - it's an unplanned outage of some internal system because some key component drifted into a bad state (e.g. database server ran out of disk / unique identifiers, call centre line to data centre was attacked by a rogue backhoe)

    To make a guess, they've probably got 10-100 key services or dependencies that need to be healthy for this function to work and they're probably running 1,000-10,000 different software platforms internally (not instances but different software applications).
