In this talk we discuss some aspects of the local-global principle for integral points. In particular we will see concrete examples of Brauer classes obstructing the Hasse principle and discuss obstructions to the local-global principle more generally. Some of our focus will then be on the case of systems of two (inhomogeneous) quadratic equations - or open del Pezzo surfaces of degree four.
