What does "Could not resolve hostname" mean?
This error indicates that the domain name servers (DNS) that translate your domain name into an IP address failed to respond during the test cycle.
You will need to contact your DNS service provider (which is often your domain registrar) to determine the cause of the outage and any corrective action taken.
You may find that during a DNS server outage you can still access the server from your computer. This is because both your operating system and your ISP cache DNS records for up to 24 hours, meaning that they already know the relevant IP address and can continue without contacting your DNS server.
Wormly monitoring nodes respect the (time to live) TTL period defined by your DNS servers, and so also cache DNS records.
