Flux compactifications of IIA supergravity on orientifolded -manifolds have been argued to allow for classical 
vacua with moduli and scale-separated 
vacua with full moduli stabilisation. To further uplift these vacua to meta-stable 
vacua using anti-D2 branes, warped throats are desirable. We study the flux-stabilisation of local “CGLP-type” throats in compact spaces, and discuss consistency constraints on anti-brane uplifting. Despite the classical vacua being free of tachyons, we find that uplifting from anti-branes down warped throats is forbidden. If instead we rely on hypothetical vacua that arise from quantum corrections to the classical vacua, we find that (similarly to the 4d analogues) consistency constraints point in opposite directions. However, there is potentially an advantage over 4d when it comes to concrete fine-tuning freedom of numbers, such as tadpole constraints.
