Glad it's back up and fixed!

This type of problem is surprisingly more common than most think. The fact that some will regain full access before others...or will lose access before others can be explained in how the internet works.
When a host redirects a domain name, without blocking the actual service, it takes a while to update all the Domain Name Servers (DNS) in use by ISPs. Those without the update will still access the pages as intended, those updated quickly will lose service almost immediately. The same thing happens in reverse when the DNS is updated to restore normal service.
Some DNS are updated only once or twice a week...so if the "cancellation" happens just before an update those served by such a DNS will lose service almost immediatley and then might wait almost a week before the "restoration" update.
Most people in North America and Western Europe are served by a DNS that updates at least once a day, many broadband customers are served by a DNS that is updated every 15 minutes...some update at every change.
