Uptime monitoring

I don't want a user or customer to tell me their web site is down, I expect the computer to tell me first. There are services who do this for you, for free. I use two:

• UptimeRobot
• StatusCake

UptimeRobot

The free version will run up to every five minutes and check the HTTP version of your site is up. Does not seem to detect SSL security expiry or ale to check if one's email server is down.

Provides a standard link for your status page, like this: https://stats.uptimerobot.com/G6yoXs15DE

It also allows a customised URL, like this: https://allpages.s-and-j.co.uk/ but I could not work how to set up the SSL certificate to make that work. Instead, I have made it a redirect to the standard link.

StatusCake

I have three public links set up:

• SGR web sites - https://uptime.statuscake.com/?TestID=AzlnukNsd0 or https://sgr-sc.s-and-j.co.uk/
• All sites - SGR, Conscience, Simon - https://uptime.statuscake.com/?TestID=fh1zha9Y2A or https://statuscake.s-and-j.co.uk/
• Conscience web sites - https://uptime.statuscake.com/?TestID=oYcIpc3muj or https://conscience.sandjltd.co.uk/

It does not do SSL monitoring in the free plan.

It does 'domain monitoring' but only does one domain.
