OnlineOrNot provides uptime monitoring and status pages.
Our uptime monitoring lets you continuously monitor any website, API server, or cron job/scheduled task. It notifies you instantly in the case of any problems - whether that's a timeout, 4xx/5xx error, or your SSL certificate expired.
Our status pages allow your team and your customers to check on how your service is running, and get notifications whenever an incident is created, updated, or resolved.
If you have any questions at all - feel free to email me at firstname.lastname@example.org.
