Sorry it took this long to figure out the downtime that lasted just over 15 hours today. Totally my fault.
At first, I forgot about the notification from my host about the server IP changing. Then, I go and update only the A record for the domain, not realizing that since I'm using custom nameservers, that I also needed to update the IP address on the glue records for the domain...
Anyway, only when the registrar reminded me of that, the site was back up seconds later.
