How we measured this
Japan readings on this page come from RealUptime's own Tokyo probe against AT&T's public endpoints. They are not user reports, and they are not AT&T's own status page.
See AT&T's full check readings, the 90-day history by region, or the outage tracker methodology.
Japan readings here are taken from that country and show the time of the last one, but AT&T has not yet accumulated enough continuous history for us to publish this page to search engines.
