Oh Dear

Changelog for October 2nd, 2026

Up to 90 days of uptime history on status pages, a CNAME takeover fix, and various improvements.

New #

  • Status pages can now show 30, 60, or 90 days of uptime history.
  • Status page icons can now use custom colors for ok, warning, and danger states.

Improvements #

  • Teams can now have up to 10 monitors sharing the same URL, up from the previous limit.
  • Increased the maximum interval between uptime checks to 24 hours.
  • Documented how hourly reminders work while an uptime monitor stays down.

Security #

  • The MCP consent screen now shows the destination of a redirect before you approve it.
  • Fixed a security issue where an abandoned status page CNAME record pointing to Oh Dear could potentially be taken over by a third party.

Fixes #

  • Fixed an issue where application health checks could send a "problem resolved" notification even though no problem was ever reported, when a failure threshold was set.
  • Fixed a bug where notifications appear duplicated in the sent notifications modal.
  • Fixed an issue where updating a monitor's URL via the API could fail if the team was already at its limit of monitors sharing that URL.
  • Fixed an issue where an unfinished two-factor authentication setup was incorrectly shown as enabled; it now resumes where you left off.
