Around half of the baryonic matter in the universe is expected to live in low density, high temperature filaments stretching between galaxies. This 'missing' matter (or warm/hot intergalactic medium) is so hot that it was not detected prior to the present generation of high resolution UV and X-ray telescopes. In X-rays, hot absorbing gas has been detected in the vicinity of the Galaxy and along the sight lines towards X-ray bright AGN. The local gas can be associated with the hot phase of a local filament of IGM (at z=0). The extragalactic gas can be associated with the hot phase of filaments between us and the X-ray bright AGN. We discuss X-ray detections of the hot phase of the IGM, around our Galaxy (at z=0) and beyond (at z>0). We review the observations and show that that the local hot gas can have multiple identities, including a local IGM filament and we show that there is considerable ambiguity in X-ray detections of extragalactic IGM. The hot missing matter at z>0 may still be missing.
