It seems to be working just fine now. Have you flushed your browser's DNS cache? – toomanyairmiles Mar 12 '12 at 10:49

Because DNS records are systematically cached, it generally takes up to 48 hours for changes to propagate throughout the rest of the system. Flushing your browser's DNS cache may not necessarily resolve the issue right away, due to the various different levels at which this caching happens (your records may be up to date with respect to your ISP, but your ISP may not have received the changes just yet themselves).

It looks as though everything is in order now, however, and the behavior you describe is normal for that span of time. Generally, unless it is taking significantly more than 72 hours for your changes to take effect (which you can test with tools like What's My DNS), there is no cause for alarm.
