1. A method comprising: computing a first set of network instability metrics, corresponding to a first set of related network prefixes sharing a first common property, based on a first plurality of route changes associated with the first set of related network prefixes; computing a second set of network instability metrics, corresponding to a second set of related network prefixes sharing a second common property, based on a second plurality of route changes associated with the first set of related network prefixes; configuring a graphical user interface (GUI) to simultaneously display: (a) a representation of the first set of network instability metrics associated with the first set of related network prefixes, and (b) a representation of the second set of network instability metrics associated with the second set of related network prefixes, wherein the method is performed by at least one device comprising a hardware processor.
