What if a satellite goes offline?

For further reading the satellite documentation is quite helpful - Understanding Satellites and Metadata Regions in the Network - Storj Docs

A specific Satellite instance does not necessarily constitute one server. A Satellite may be run as a collection of servers and be backed by a horizontally scalable trusted database for higher uptime. Storj operates clusters of Satellites in regions, with all Satellites in a region sharing a multi-region, distributed back end.

For more detail on ‘what a segment is’ this post should help…

At the highest level, an incoming object stream is broken into 64 MB ranges of bytes we call “segments”. … Most of our internal accounting really handles segments and not objects.

Within a segment, the encrypted data is broken into “stripes”, which are just a few KB. Each stripe is erasure encoded into “erasure shares” and added to outgoing streams to individual storage nodes called “pieces”.

As @littleskunk noted the segment fee was due to some customers uploading a large number of tiny files which created excessive overhead in the satellite metadata databases.
