How this was measured

Views are Wikimedia's own pageview counts for en.wikipedia, filtered to agent=user so automated traffic is excluded. The baseline is the median of the previous 60 days, which is used instead of the mean so that an earlier surge cannot flatten a later one. The multiple is the day's views divided by that median.
