Shadowbringers
Dungeons: Matoya's Relict and Paglth'an (WAR) has been soloed.
Trials: Nothing confirmed.
8-man: E3N, E4N confirmed (PLD).
24-man: Nothing confirmed.

The following instances are all confirmed unsoloable:
No 24-mans are queueable solo. LotA requires a minimum of 12 at the Atomos. WoD requires 3 or 4 for that Atomos. WCoM requires at least 3 for the Atomos. DS can't be done by anybody other than a healer due to doom on the first boss, but other mechanics may prevent soloability (it can be beaten by 3 people though). Royal City requires 3 to get through the sewers + add phase on Rofocal. Orbonne has insta death mechanics on the 2nd boss that can't be avoided.
Trials: Susano (Story/EX), Yojimbo are unsoloable due to mechanics. Suzaku and Seiryu EX are unsoloable due to damage (boss puts on a physical resistance down debuff), Byakko EX is unsoloable due to damage (first slam gives a physical resistance down debuff, second slam does over 500k damage unmitigated).
8-Man: A4S due to Nisi on the 4th leg. O11N & O11S due to Level Checker mechanics. O12N due to damage from boss tether.

Instances I believe may be soloable that need checking:
Omega Raids: O7. Difficulty now due to outgoing damage (from being unable to close gates in Bibliograph phase).
