Currently got :

District is part closure, part suspended, minor delays*
Overground and Met planned closure, part closure
Piccadilly part closure minor delays
TfL rail reduced service
4 lines good service (Jubilee, Victoria, Northern, Tram)
Not sure a potential passenger is going to consider severe delays and reduced service that differently, so why distinguish
*District Line: No service Earls Court to Kensington Olympia due to train cancellations. No service between High Street Kensington and Edgware Road due the unavailability of control room staff. No service between Tower Hill and West Ham due to planned engineering work. Minor delays between Earl's Court and Wimbledon due to an earlier signal failure at Parsons Green. Tickets valid on local buses and South Western Railways.
Realtime Tube, Overground, Elizabeth line, DLR & Tram travel updates.

Wonder why “Planned closure, part closure“ is used, sort of implies there is unplanned part, without saying so, so why not just part closure or partial closure if too scared to say unplanned
