Mark Website as Down when Domain Expires
When a domain has expired and is pointed back to something like a GoDaddy parking page, the monitor shows the site as up. See attached screenshot.
For all intents and purposes, this should really show the website as down. It's easy to overlook for too long when you manage 80 - 100+ sites.
I am gonna mark this one as resolved as we've now implemented the domain expiration alerts in https://updown.uservoice.com/forums/177972-general/suggestions/36631813-warn-about-expiring-domain-names. It is not exactly the same thing because it will not consider the website as "down" if it still responds with 200OK but at least you can get notified. Also in the example shown in this screenshot, such error would definitely be considered as "down" as it's not even connecting, the monitoring was likely still 200OK because the configured DNS TTL had not expired yet and was still returning the old IP.
