\emph{understanding} and \emph{predicting} changes to catchments as
sites are added or removed has been challenging.  Current tools such
as RIPE Atlas or commercial equivalents map from thousands of vantage
points (VPs), but their coverage can be inconsistent around the globe.
This paper proposes \emph{Verfploeter}, a new method that maps anycast
catchments using active probing.  Verfploeter provides around 3.8M
virtual VPs, $430\times$ the 9k physical VPs in RIPE Atlas, providing
coverage of the vast majority of networks around the globe.  We then
add load information from prior service logs to provide calibrated
predictions of anycast changes.  Verfploeter has been used to evaluate
the new anycast for B-Root, and we also report its use of a 9-site
anycast testbed.  We show that the greater coverage made possible by
Verfploeter's active probing is necessary to see routing differences
in regions that have sparse coverage from RIPE Atlas, like South
America and China.",
