I would take their displayed uptime with a huge grain of salt. The other day Claude Code and claude.ai web were completely unavailable for me (Claude Code got into logged out state and couldn’t even log in) for at least two hours, they showed hours of “elevated errors”, yet not a single minute of downtime was recorded. And then there was yet another outage finally with recorded downtime a few hours later…
