Quick question -
We have a site we recently migrated to one of our servers. We changed the nameservers about 3 days ago - and on all of the computers we've tried it's been pointing to the new location properly.
...except for at the client's place of business.
When they go to the domain (xyz.com or the www sub) - they still get the old site across the board - at all computers.
I don't know much about DNS issues - apart from "change the nameserver, set the A tag, etc. etc. etc" - the actual mechanics of getting the site ported from one location to another.
What could conceivably be causing this? Is it an issue of their provider not updating their DNS records - and if so - how would you fix this?
