I also don't just mean outages like this... it's clear that Microsoft GitHub has been cramming a bunch of new stuff into the UI and not really treating it with care. I notice very amateur UI bugs, misalignment, bad spacing, overlapping elements, etc. all the time now. It was clear that old GitHub passed through a professional designer's eye quite carefully (or maybe just a developer with extreme attention to detail).

The inconsistencies aren't deal breakers - github still has a very pleasant UI overall - but they do makethe website feel more and more unpolished each day
