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