The numbers are problem reports that users sent to a public outage-reporting service, counted in 15-minute windows and kept as this site's live page showed them. A spike counts as an outage when reports are more than twice the usual level and far above the day's average. Reports show that many people had trouble at the same time, not what caused it; the service's own status page is the place for that.
