DNS Not updating

I’ve recently migrated some websites to a new host and this a new IP address. All the Nameservers have been updated to point to the new hosting yet one website does not appear to be updating when using the Glide DNS. If I use any other DNS such as Google, GigaClear, Zen etc (Tested from other client servers) the IP address resolves to the new location, but not anything going via Glide. Nameservers were changed 48 hours ago. I’ve flushed DNS servers etc but still cannot get this one domain to resolve to the new hosts via Glide (Our business internet connection)

I think you can chat with the support team to request further help.
